摘　　要：微电网包含众多特性迥异的分布式电源且运行控制策略复杂,需要借助各种试验手段对控制系统进行验证。动模试验平台和半实物仿真平台由于体积庞大、造价高昂的缺点,制约了其在工程中的应用。基于可编程逻辑软件搭建了包含分布式电源、负荷和控制器的微电网仿真系统。以某独立型微电网为例进行仿真试验,试验结果表明,基于该系统可开展分布式电源建模、系统控制策略设计、软件调试及仿真等多种形式的试验验证,测试并验证控制理论、控制策略,仿真验证后的控制逻辑可直接在控制器中动态加载运行。Since a microgrid contains many distributed generators with different characteristics and follows complex operation and control strategies,its control system needs to be verified by various experimental approaches.Dynamic simulation experimental platform(DSEP)and hardware-in-the-loop simulation(HILS)are rarely used in engineering scenarios due to their large sizes and high costs.A simulation system based on programmable logic software for the microgrid including distributed generators,loads and controllers is established.In the simulation test on an isolated microgrid,the distributed generator modelling,system control strategy design,software debugging and simulation of the microgrid are carried out,and the control theory and control logic are tested and verified.The control logic after the simulation and verification can realize the dynamical loading and operation in the controller directly.
