Application Of Magnetic Controllable Reactor Of Reactive Power Compensation In Power System

A main measure that keeps the high quantity of power system is using the reactive power compensation devices. Nowadays, it is also an important subject related to such fields as power system, electric automation, etc. At the same time, more and more researchers pay attention to the reactive power compensation.Aim at the existent problem of reactive power compensation devices, this paper analyses a kind of dynamic reactive power compensation device based on MCR (Magnetic-Value Controllable Reactor). It is developed with power electronics technique and found on the breakthrough of traditional saturation reactor. What is more, it overcomes the shortcoming of traditional saturation reactor such as slow response speed, high loss and harmonic distortion etc. The dynamic reactive power compensation device not only has higher reliability and lower harmonic distortion but also can regulate the reactive power smoothly. So the devise can be used widely in the power system.First this paper introduces the background and research significance of this subject and points out the existing problems using traditional reactive compensation mode, its present situation and developing trend. What's more, the structure and basic principle of MCR is discussed in this paper. The theoretical analysis of MCR and its advantages are also introduced in it. Futher more this paper recommends the key technology of the development which based on the 35kV dynamic reactive compensation system with the MCR. The voltage reactive-power integrated control strategy is focuses on the analysis. In addition, the test state and test result of dynamic reactive compensation system in Baique transformer substation is presented in this paper. The Economic benefit and social benefit in in Baique transformer substation of this system is also presented. At last this paper summarizes the work and prospect the problem which still need to study and resolve.
