Technical Scheme and Operation Performance of Dynamic Voltage Regulator and Fault Current Limiter
摘要
Abstract
To enhance the safety and economy of distribution system by optimizing its bus voltage profile and power fac-tor and reducing the short-circuit current,a circuit scheme of dynamic voltage regulator and fault current limiter (VR&FCL)is developed based on the coordinated control of output reactance by means of fast mechanical switches and thyristor valve. With the combination of step regulation and flexible regulation,an integrated multi-objective control strategy is worked out. Therefore,the hybrid functions such as bus voltage regulation,power factor correction and fault current limitation are realized. A simulation model including a test system,VR&FCL and its control strategy is estab-lished using PSCAD-EMTDC,and the output characteristics of equipment under different scenarios of distribution net-work are analyzed through simulations. Results show that VR&FCL can work well with the preset designed functions as well as accurate and fast response.关键词
