Remote real-time collection, monitoring and management of power consumption information for SHP power stations

Common management solutions

1, manual telephone dispatch management

These power stations are located in remote areas with low construction investment, small power generation, simple equipment and operation management, low degree of automation, and poor communication conditions. The measurement of on-grid electricity is simple. Most of them use ordinary three-phase mechanical metering, manual meter reading or manual telephone meter reading, and the monitoring of the power quality of the Internet is hardly conducted and managed. Even the scheduling order is notified by telephone instead of The load changes automatically.

The disadvantages of this management are:

u The overall grid security is not high;

u Communication is not timely and automatic power adjustment cannot be achieved;

u The workload of manual meter reading is inaccurate, and the measurement is inaccurate, which directly affects the settlement of on-grid electricity and electricity bills;

u The power supply quality of the power station cannot be monitored in real time.

2, remote optical fiber scheduling communication management

According to the regulations of the State Grid Corporation of China and the Electricity Regulatory Commission on power generation companies, power plants with a generating capacity of more than 10,000 kilowatts are dispatched by the Provincial Company Dispatching Bureau, and the power generation capacity is dispatched to the dispatch center of the local electric power bureau below 10,000 kilowatts, and Requires that two sets of communication channels (optical fiber dispatching private network) are required to communicate with the dispatching bureau, receive scheduling commands, upload relevant power generation information, and have special electric energy collection cabinets to measure collection at the outlet platform or at the substation that accesses the large network. Internet power and internet power quality.

The characteristics of this management method in terms of management and economic benefits:

u Accurate measurement, timely collection, easy calculation and transmission of electricity charge;

u High safety requirements;

u timely communication, real-time monitoring of power generation quality;

u The corresponding equipment investment is high, increasing the burden on the power station;

u The corresponding equipment has high technical and operational requirements, and it is complicated and difficult to master and use.

Recommended program

The on-grid power management and real-time power quality monitoring and management of these small and medium-sized power stations cannot rely on manual management to be accurate and timely, but the construction of fiber-optic dispatching private networks will require power companies and power stations to increase their capital investment. The burden on both parties, therefore, requires a set of acquisition and monitoring system solutions that can meet the power company's timely and timely collection of grid-connected electricity, real-time monitoring of online power quality requirements, and control of construction costs so that power companies and power stations can afford. Provides reliable means and basis for power company's power station (small hydropower station) management (settlement management) and dispatch management.

With 10 years of accumulated experience in the power industry, our company has accumulated a wealth of business resources and a variety of mature applications. Among them, ordinary three-phase electronic meters and special collection and monitoring terminals for power plants are used as hardware devices, electric energy collection platforms and management analysis platforms are used as main station management software platforms, and GPRS\CDMA communication technologies are used as data transmission channels to form a power station. Power remote real-time acquisition monitoring and management system—provides a set of mature and stable solutions for collecting power for on-grid power generation of small-scale power plants (plants) and remote real-time monitoring and monitoring of power quality on-grid.

System Overview

The “Long-Term Real-time Acquisition Monitoring and Management System for Power Generation of Power Stations” can remotely collect and remotely transmit power generated by power plants (plants), on-grid power, and plant power, and conduct real-time online monitoring of power quality and on-grid power quality. Monitor the three-phase balance, current, and voltage fluctuations, and perform statistical analysis, alarms, and other information on abnormal conditions.

System Features:

u Adopt GPRS remote wireless data transmission technology to collect data remotely without human intervention and without user intervention

u Understand the working conditions of the power station in a timely manner, and timely understand the power generated by the power station, on-grid electricity, and self-use electricity.

u Remote real-time monitoring and monitoring of the production and operation of the power station to prevent abnormal power generation.

u remote real-time monitoring of the quality of the electrical energy and Internet power, voltage, current changes;

u Use ordinary three-phase multi-function electronic meter and GPRS communication, low investment cost, high cost performance

u The system can access the dispatching system of the power company and become an important basis for scheduling management.
