Matching Characteristic of Constant Voltage Source Excited Filter in Power System

Abstract:

Filters between voltage source converter and the batteries in power system can be categorized into constant voltage source excited filters. The paper discusses the importance of the matched structure and parameters for power filters. The relation between matched structure and filters output characteristic is demonstrated and the design principle is introduced. The work above proved that even if the filters are designed for the same transfer function, so long as filters load resistance is different, their designed parameters are also different. Traditional power system filter seldom consider its both ends load matching characteristic. When the difference between filter's load characteristic and practical system equivalent impedance are large, the actual filtering effect becomes worse, current loss arises and even there may be the possibility of resonance. As the lack of energy resource and energy crisis is gradually becoming a serious problem, energy conservation is important. Constant voltage source excited circuit configuration model is established through the simulation and test. The results show the validity and feasibility of the method that filter should be designed the according to its load characteristic in practical application.
