| 摘 要： | 用户在市场环境下与电网公司的博弈过程中，将倾向于在电网负荷较高时启动用户自备的分散电源（DG）并网。文中首先建立了含异步型分散电源（IDG）的配电网启动模型，根据该模型对杭州局某10 kV配电网进行了多IDG的启动模拟，仿真结果表明，多IDG同时启动将造成并网过程中的电压骤降或电流增大，对系统运行和保护配置等都将产生重要影响。随后，提出了采用并联电容器组就地补偿方法和采用自耦减压启动器降压启动的解决方法，并分别进行了算例仿真研究。

| Abstract: | When bidding with the distribution utilities in an electricity market,distributed generators(DG),which are controlled by customers,tend to start and connect to the grid when the load demand is high.A starting model of induction distributed generators(IDG)in a distribution network is firstly proposed.Based on the proposed model,the starting transient of several IDGs in a 10 kV system of Hangzhou Power Grid is simulated.The results show that simultaneous starting of IDGs may lead to voltage sags or current in... |
