Quasi Synchronization Strategy Design of Multi Diesel Generators

针对柴油发电机多机并联经济性运行问题,设计了一套通用化柴油发电机同期并机以及协调功率分配策略,实现不同配置多柴油发电机组供电系统的同期并网和自动功率分配,基于SIMULINK仿真软件搭建5台不同配置柴油发电机并车运行模型,准同期并网法实现各机组的组网运行,并设计一套协调控制策略,实现多柴油发电机协同经济运行,通过仿真验证所设计并车策略的可行性。

Aiming at the economic operation of diesel generators in parallel,this paper designs a universal strategy of synchronous and coordinated power distribution for diesel generators,to realize simultaneous grid connection and automatic power distribution of power supply system of multi diesel generator set with different configuration.Based on Simulink simulation software,5 parallel operation models of diesel generators with different configurations are built,the networking operation of each unit is achieved by quasi synchronous grid connection method,and a set of coordinated control strategies are designed to realize the coordinated economic operation of multiple diesel generators.And the feasibility of the designed strategy is verified by simulation.
