Simulation Study on the Control Strategy of Parallel Systems in Switched Reluctance Generators

摘要

To enhance generating capacity and reliability of multi-machine parallel power generation, implement the efficiency optimization, a current distribution control method based on differential evolution (DE) algorithm is proposed for the switched reluctance generator (SRG) in parallel. The load current is stabilized by the maximum value current sharing control (CSC) firstly. Then, the current distribution control method is adopted, which can adjust the reference current of each parallel generator in the current distribution part, so as to change the working point of each generator and implement the optimization of parallel system efficiency. The performances of the proposed control method are evaluated in detail by the simulation, and comparison with traditional current sharing control is carried out as well.
