The unattended power stations are more and more popular in but how to make the smart grids, unattended power stations visual is a big problem. So the build of video and environment surveillance systems is an effective solution. But due to too many manufacturers the video and environment surveillance systems of power grids have been faced a huge number of problems, such as the issue of interconnection and interworking. In order to solve this problem, we designed a test system of video and environment surveillance system to test the consistency of device communication protocol to ensure interoperability of equipment. The test system is to simulate the real equipment of video and environment surveillance systems, so tests in the laboratory can replace that in the real operating environment.

Along with the increasing use of cables in power grid and the increasing ration of distributed power sources’ synchronization, such as small hydropower’s synchronization, increasing the reactive power transmission on the line, make it difficult to achieve the balance of reactive hierarchical partition. Take a certain region’s power grid for actual examples, after the installation of magnetic control reactor (MCR), using immune genetic algorithm (IGA) to coordinate the capacity of magnetic control reactor and the existing reactive power resources, the results show that the magnetic control reactor does much good to absorb the system’s excessive reactive power and limit the voltage’s increasing.
