摘要

本文对孤岛微电网上两台微型水电站并联运行的控制策略进行了实验测试。这两个mhpp都配备了驱动感应发电机(IG)的等速涡轮机。所提出的控制系统是电压源逆变器(VSI)和转储负载(DL)的结合。VSI在恒定频率下工作，从而稳定了MG频率。电压调节是由DL来完成的，通过耗散超过的有功功率。进行实验测试是为了突出控制系统对重要的过渡状态的响应，例如第二台发电机连接到主发电机或突然接通和关闭大负载。

Experimental testing of an isolated micro-grid supplied by two micro hydro power plants

This paper presents the experimental testing of a control strategy for the parallel operation of two micro hydro power plants (MHPPs) on an islanded micro-grid (MG). The two MHPPs are equipped with constant-speed turbines that drive induction generators (IG). The proposed control system is a combination between a voltage source inverter (VSI) and a dump load (DL). The VSI operates at constant frequency, thus stabilizing the MG frequency. The voltage regulation is accomplished by the DL, by dissipating the exceeding active power. Experimental tests are performed to highlight the control system response to significant transitory regimes such as the connection of the second generator to the MG or a large load being suddenly switched on and off.
