Research On Multiple Objective Controlled Fault Current Limiter Applied In Low Voltage Distribution Network

The new type FCL this paper presented is one kind of FACTS, which is an integrated application technology. It could solve many kinds of problems resisted in power system, such as voltage sag and harmonics, by injected a proper voltage vector which is required. This paper mainly achieved the multiple objective controlled algorithms during different kinds of system malfunction, and supplied the optimized topology and parameter. The main job of this paper is as follows: Introduced the actuality of fault current limiter in detail, the current research actuality as well as the reason and meaning to investigate on this topic; Do research on and presented the basic structure, principle of operation and mechanism of compensation of this multiple objective controlled FCL. And then compared many kinds of control strategies and established a single phase model on the theory which presented before; Analyzed the energy management part of this device, and find a way to solve the problem, and then demonstrated the method; Prospected the application of this new theory.
