Thermal power generation enterprises will be staged in the high-voltage frequency conversion market

Market behind the standard

Recently, an industry standard that has a major impact on energy-saving and consumption reduction of thermal power generation enterprises--the report of the "High-voltage Inverter Standard for Thermal Power Plant Fans and Pumps" is being submitted to the China Electricity Industry Federation Standardization Center. According to the procedure, this industry standard will be submitted to the National Development and Reform Commission for approval by the CEC Standardization Center. For domestic high-voltage inverter manufacturers, this means that a large market is being generated.

It is understood that this new industry standard was jointly drafted by Huazhong Power Grid Co., Ltd., Hubei Sanhuan Development Co., Ltd. and Wuhan University, and received the relevant manufacturers from Power Generation Group, Electric Power Design Institute and domestic high-voltage inverter in late August. Further review by technical experts.

According to the national "Research on the Ways and Countermeasures of Motorization of Motor Speed ​​Control Technology", 66% of China's total power generation is consumed on electric motors. At present, China's total installed capacity of electric motors has exceeded 400 million kilowatts, and high-voltage motors account for about half. The load of nearly 70% of high-voltage motors is driven by fans, pumps and compressors, and half of them are suitable for speed regulation, that is, about 75 million kW. The high voltage motor is in a state of wasted operation. From the general use of the current high-voltage inverter, the average power saving can reach 30%. Therefore, whether in the new construction project or in the technical transformation project, the energy-saving effect of the high-voltage inverter system is not mentioned. Yu. Some people in the industry have a conservative expectation that the annual average market capacity after the high-voltage inverter market is stable should be between 8 billion and 9 billion yuan.

With enough market, standards will emerge.

The imminent generation of thermal power inverter standards means that power generation companies and inverter manufacturers value this field, which means that the government is paying close attention to this field. The participation of professional thermal power design units in the review means that new thermal power design rules will undergo new changes in the future. In the future, thermal power designers should consider designing energy conservation together. In fact, this change has already occurred. The inverter industry insiders told reporters that the thermal power design experts considered the high-voltage frequency conversion energy-saving facility when designing the Henan Yinzhou Power Plant.

"We hope that the government can stipulate an energy saving rate, which can be based on the region, not necessarily the mandatory use of an energy-saving product. As a result, there are naturally many high-voltage inverter products in the field of energy-saving options." At the bid evaluation meeting, a certain inverter manufacturer expects it.

Thermal power saving orders are getting thicker

This new market emanating from the power industry comes from the advancement of electricity reform. After the reform of the power system has completed the separation of the plant and the network, the main body of the power generation market is diversified. In addition to the rising price of coal in the upstream, the end market of the power supply also has an inflection point. The rapid expansion of each power generation group itself also brings sequelae, and so on. All of this has led the power generation group to pay close attention to the production costs of the power plant that can bring cash flow to it.

In China's power generation composition, thermal power accounts for more than 70%, while in general thermal power units, its power consumption generally accounts for 4% to 7% of power generation, and high-voltage factory electric motors that drive large-capacity fans and pumps are auxiliary. The power consumption accounts for about 80% of the electricity used by the plant. The high-voltage inverter is a "library" to reduce the power consumption of the plant. The original purpose of the inverter is speed control, but for the current Chinese market, its greatest value is energy saving. It is understood that the high-voltage inverter is a typical "double high product", that is, high-tech content and high price, so its application in China has been slow. However, in recent years, due to the energy bottleneck, the climate of the energy-saving market has gradually formed, and the government has begun to pay close attention to the field of energy conservation.

In the first half of this year, in order to implement the “medium- and long-term special plan for energy conservation” and achieve the planning objectives, the National Development and Reform Commission initiated the ten key energy-saving projects proposed by the plan, the fifth of which is the energy-saving project of the motor system, encouraging the promotion of variable-frequency speed-saving energy-saving technologies and formulating relevant Supporting measures such as economic incentive policies and technical policies, and improving the motor energy efficiency standards system. During the “Eleventh Five-Year Plan” period, the operating efficiency of the motor system was increased by 2 percentage points, and the annual energy saving capacity was 20 billion kWh.

At the beginning of this year, Datang Power Group opened an order for nearly 100 million yuan of inverter conversion projects to high-voltage inverter manufacturers. It is reported that it will open a giant order next year. According to sources, Huaneng Group, which used high-voltage inverters in 2001, has begun to pay attention to the high-voltage inverter product line this year after several years of shutdown. However, some power plants with more flexible and filial mechanisms are moving faster in this respect. Many power plants have begun to enjoy the energy-saving results brought by high-voltage inverters.

On July 1 this year, Siemens acquired the American Robincon company. The latter is a well-known big-name in the field of high-voltage frequency conversion. Its market share in China has been ranked first for many years. This major acquisition of the international frequency conversion industry clearly means that Siemens and Robin Kang are two big players with different advantages. The spirit began to ridicule the gold in the Chinese city."

Custom Piezoelectric Components

The piezoelectric ceramic sound-generating element, especially a lead-free piezoelectric ceramic sound-generating element, is mainly composed of metal flakes and piezoelectric ceramic flakes. The sound pressure generated by this new structure piezoelectric sounder is proportional to the number of piezoelectric ceramic sheets. By increasing the number of piezoelectric ceramic sheets, the required large sound pressure is easily achieved.
