虚拟同步发电机并联系统的功率均分研究
Research on Power Sharing of Parallel System of Virtual Synchronous Generator
摘要
Abstract
Based on the droop characteristics and rotational inertia external characteristics simulation of synchronous generator,distributed inverter unit can show the characteristic of a synchronous generator,the virtual synchronous generator(VSG)parallel system has problems such as circulation and the average power is not reasonable. according to the droop equation and single small signal equations based on active frequency droop control ,the power sharing formula of VSG parallel system was derived,parameter design formula was also suitable for the VSG parallel system with the same and different capacity,and the power distribution of VSG could be realized according to their capacity in the transient state and steady state. Simulation and experimental results show that the parallel VSG parameters designed according to the power sharing formula proposed,can achieve the power sharing of parallel VSG systems with the same and different capacity.关键词
