According to the "Shanghai Securities News," the "Shanghai Securities News," according to "Shanghai Securities News" report, China's National Energy Administration's decentralized power generation management measures introduced as soon as possible in July, will be through subsidies, extra power grid sales to the grid and other measures to stimulate the distribution Energy development. This will help to rationally control the total energy consumption. The approach has now entered the consultation stage, marking the biggest obstacle to the development of distributed energy will be cleared.
The report quoted officials from the Energy Bureau as saying that if the distributed generation reaches 5% of the existing generation, 70 million tons of standard coal can be replaced, which is equivalent to the construction of 64 600,000 kilowatts of large coal-fired units.
The so-called distributed generation refers to a power generation system or an integrated power supply system that is built in the vicinity of a user and the excess power is sent to the local distribution network in addition to its own use. Its main feature is the use of new types of power generation technology, which is conducive to environmental protection, energy efficiency, up to 60-90%.
The development of distributed energy in China has just started. Taking natural gas distributed power generation as an example, the installed capacity is currently about 5 million kilowatts, which is less than 1% of the national total installed capacity. The Energy Bureau proposed last year that it plans to build 1,000 natural gas distributed energy projects by 2011. By 2020, it will promote the use of distributed energy systems in large cities, with an installed capacity of 50 million kilowatts, a tenfold increase from 2010.
National Ministries Accelerate the Drafting of Relevant Regulations Distributed Energy Development Enters the Fast Track The editors are rapidly infiltrating into a powerful power system in accordance with the concept of distributed energy. However, the biggest obstacle to the development of distributed energy is the grid connection and the Internet. The resistance comes from the power system. Nowadays, under the favorable situation of the “12th Five-Year Plan†promoting the transformation of energy production and utilization methods, the attitude of the power system is rapidly changing. From the previous concerns and exclusion, it has become a positive and active response to participation. Distributed energy in China is enjoying great development. It is not difficult to foresee that the previous obstacles to the development of distributed energy will be dispelled no matter if the system, technology, or interests are constrained.
"Since last April, the National Energy Administration issued the "Guideline for Soliciting Opinions on the Development of Distributed Natural Gas Guidance," the National Energy Administration drafted the "Guidelines for the Development of Distributed Energy for Natural Gas," and is currently taking the internal approval process." April On the 12th, Yang Lei, Director of the Oil and Gas Division of the National Energy Administration's Oil and Gas Division, was introduced at the "2011 Seminar on Cold, Heat, and Electricity Combined Technology" in Beijing.
Relevant laws and regulations are accelerating the drafting. In December of last year, the State Council Energy Research Institute and the National Energy Administration jointly held a seminar on distributed energy. The National Energy Administration Chief Engineer Wu Guihui gave suggestions. The government and enterprises must work together to accelerate the development of high-speed railways. Distributed energy construction.
Although the development strategy of distributed energy has been included in the national “Twelfth Five-Year†development plan, so far, there is no domestic policy on distributed energy or distributed natural gas. The lack of relevant national policies and the inadmissibility of grid connection and access to the existing electric power system have resulted in the slow development of distributed energy in China over the past 10 years.
From March 1st this year, the "Technical Regulations for Gas-Fired Thermal Power Triple Supply Project" approved and approved by the Ministry of Housing and Urban-Rural Development began implementation. This regulation is applicable to the design, construction, acceptance and operation of a distributed thermal energy system with natural gas as primary energy, total generator capacity of less than or equal to 15MW, new construction, reconstruction, and expansion, and stipulating the annual average integration of the combined supply system. The utilization rate should be greater than 70%.
Recently, the Libya crisis and the Japanese nuclear power plant accident prompted the Chinese government to rethink the adjustment of new energy planning and utilization ratios. According to the previous plan of the National Energy Administration, the installed capacity of natural gas distributed energy will increase to 50 million kilowatts in the next decade. According to experts, in order to make up for the slowdown in nuclear power construction, this goal is expected to advance in the 12th Five-year Plan period. achieve.
He was informed that the "Energy Law" of the State Council Legislative Affairs Office, the "Regulations on the Management of Natural Gas Infrastructure" of the Oil and Gas Division of the National Energy Administration and the "Distributed Energy Management Regulations for Natural Gas" and the "Distributed Generation Management Regulations" of the New Energy Division of the National Energy Administration are accelerating. In drafting.
Power grid companies responded positively to the entrustment of the Department of Oil and Gas of the National Energy Administration. The State Grid Energy Research Institute last year completed the “Research on Issues Related to Distributed Natural Gas Development in Chinaâ€. The reporter learned that the "Twelfth Five Year Plan for Cogeneration and Distributed Energy Planning" compiled by the China Electricity Council has now completed the first draft. At the same time, Southwest China Electric Power Design and Research Institute has also developed a set of development distribution. Energy-related planning. Unfortunately, due to the lack of actual support, the above plans are all in the ointment and need further amendments.
Wu Guihui pointed out that power grid companies should raise awareness and create conditions for distributed energy access. The recent active performance of power grid companies is also confirming their attitude toward distributed energy.
It is reported that the State Grid Enterprise Standard "Technical Regulations for Distributed Power Access to Power Grids" (Q/GDW4820-2010) was released in August last year and began implementation. This technical standard is the first in the country. The standard stipulates the technical requirements that should be satisfied when new or extended distributed power sources are connected to the power grid through the 35 kV and below voltage classes.
According to the introduction of Wang Zhenming, senior engineer of the Beijing Economic and Technical Research Institute of the State Grid and the Thermal Power Professional Committee of the China Electrical Engineering Society, the State Grid Corporation of China has developed the “Distributed Power Connection†based on the research on the related technologies of distributed power access to the power grid. Technical Regulations for Access to the Power Grid. At present, this regulation has been submitted to the National Energy Administration for approval. If released, it will become a national standard to guide the development of the distributed energy industry.
According to this regulation, the principle of distributed power supply access to the power grid system is that the power supply can effectively transmit power and ensure the safe and stable operation of the power grid when it is integrated into the network. When more than one power supply is integrated at the public connection point, the overall impact should be considered. The total power supply capacity should not exceed 25% of the maximum load in the power supply area of ​​the upper transformer. Among them, a distributed energy source of 200 kV and below is connected to a 0.37 kV voltage level grid; a distributed power source of 200 kV or more is connected to a voltage level of more than 10 kV.
In addition, there are more specific technical standards and specifications, "including distributed power supply grid-connected characteristic testing series standards, distributed power grid-connected operation series standards, distributed power monitoring system functional specifications, and split-power monitoring devices, etc. Released in 2011-2013, respectively." Wang Zhenming said.
In addition, China Southern Power Grid Corporation is also actively participating in the construction of distributed energy stations, and recently invested tens of millions of yuan to build a distributed energy station in Foshan, Guangdong, for the three office buildings of the Foshan Power Supply Bureau compound. Electricity and cooling, the project is still in the post-production test period.
The power generation groups have stepped into the power development ideas put forward in accordance with the national “Twelfth Five-Year Plan†power development plan, demanding the optimal development of coal-fired power, and actively promoting new energy power generation. It is estimated that the proportion of coal-fired power generation will be reduced by 4 to 5 percentage points every five years. Under such circumstances, power generation groups, which have traditionally been dominated by coal-fired power generation, have had to make an early transition to a new road and natural gas has become a good choice. The growing momentum of the development of distributed energy based on natural gas is becoming more and more important.
This is also the case. The five major power generation groups are vigorously testing distributed energy projects.
According to Wang Zhenming, Huadian Group established the New Energy Development Co., Ltd. in 2007 to vigorously develop the released energy and invested in the construction of the Guangzhou University City natural gas distributed energy station. The project was put into operation in October 2009. Since then, Huadian has conducted preliminary work on more than 10 distributed energy stations in China's relatively economically developed regions (Tianjin, Shanghai, Nanchang, Shenyang, Changchun, etc.) where CNPC pipelines pass through. The projected total capacity is approximately 100,000 kW. The project will begin within the year.
Huaneng Group and Dongjiang High-tech Development Zone in Huizhou, Guangdong Province have signed a 4×390,000 kW distributed cooling, heating, and power generation gas unit distributed energy project with a total investment of approximately RMB 6 billion.
Guodian Group will also plan and construct distributed source stations in Shenzhen, Guangdong and Zhoushan, Zhejiang respectively; CPI will also successfully operate the “Distributed Energy Supply System Project†at Shanghai Gao Pei Center. In addition, the Guangdong Provincial Development and Reform Commission has approved CLP Zhuhai’s Hengqin Cold The "Cogeneration Power Station" project was included in one of the four major construction projects in Hengqin New Area last year.
In addition, the Datang Group Sichuan Branch will also invest in the construction of natural gas distributed energy in the Guangyuan City Textile and Apparel Science and Technology Industrial Park in the province, and is currently carrying out preliminary work.
It can be seen that “the above situation shows that China’s power system has already carried out a series of work on distributed energy. Under the great energy development situation, the attitude of the power system is changing and the situation is developing in a good direction,†said Wang Zhenming.
The report quoted officials from the Energy Bureau as saying that if the distributed generation reaches 5% of the existing generation, 70 million tons of standard coal can be replaced, which is equivalent to the construction of 64 600,000 kilowatts of large coal-fired units.

FTTH is an optical fiber directly to the home of the foreign language abbreviation, the Chinese abbreviation for fiber to the home. Specifically, FTTH refers to the optical network unit (ONU) installed in the home user or business users, is the optical access network in addition to FTTD (fiber to the desktop) closest to the user's optical access network application type. A significant feature of the FTTH is not only to provide greater bandwidth, and enhance the network transparency of data format, rate, wavelength and protocol, the relaxation of environmental conditions and power supply requirements, simplify maintenance and installation. Speaking of FTTH, first of all, we must talk about fiber access. Optical fiber access refers to the end of the transmission between the user and the fiber as the media. Fiber access can be divided into active optical access and passive optical access. Optical fiber transmission technology is the main technology of optical fiber subscriber network. At present, the multiplexing technology of optical fiber transmission is developing very fast, and most of them have been applied in practice. According to the depth of the user's degree of fiber, can be divided into FTTC, FTTZ, FTTO, FTTF, FTTH, etc..
