Description

Technical field [0001] The invention relates to the technical field of a clean energy remote real-time centralized monitoring system, in particular to a clean energy remote real-time centralized monitoring system. Background technique [0002] As a kind of economical and clean renewable new energy, wind power / photovoltaic power generation is more and more widely used. According to relevant statistics, in 2008, my country’s newly added wind power installed capacity exceeded 6 million kilowatts, and the cumulative installed capacity reached over 12 million kilowatts. In 2009, the newly added installed capacity reached 13 million kilowatts, and the cumulative installed capacity reached over 25 million kilowatts. It is estimated that my country's annual new installed capacity will remain at 5-8 million kilowatts. [0003] Because wind farms / photovoltaic power plants are installed far away from the load center, they are generally connected to the system through 220kV or 500kV ultra-hig...

AI Technical Summary

Problems solved by technology

[0003] Since the installation locations of wind farms / photovoltaic power stations are far away from the load center, they are generally connected to the system through 220kV or 500kV ultra-high voltage lines. The control of reactive power, voltage and network loss is more difficult

[0004] At present, the AVC and AGC control of the photovoltaic power station of the wind farm in the power grid under the jurisdiction is being implemented, and the operating system is formed through the combination of AVC and AGC. However, the control effect of the existing system is not ideal, the voltage fluctuates frequently, and the voltage qualification rate is low. Some systems have low security performance, which is easy to cause data changes and leaks, increasing the probability of network loss, and the existing system is complex in operation and cannot adapt to various complex structures. For this reason, we propose a remote real-time concentration of clean energy monitoring system to solve the above problems
