Excitation Systems Coordination for Back-to-Back Starting for Pumped Storage Units
摘要
Abstract
In the process of back-to-back starts, the excitation systems coordination between two units is a key issue. Using the state equations of synchronous motor, a mathematical model of back-to-back starting was established in this paper. Based on above research, back-to-back starting process for pumped storage units under different conditions were simulated, which includes the normal starting and starting processes with motor de-excitation and braking and so on. With the research of simulations, the problems of excitation systems coordination between two units were recognized, and an appropriate solution for this problem is proposed. By adding a hard-wire circuit between LCU and the tripping circuit and each of these circuits is added with an additional relay, two excitation systems can be removed simultaneously.关键词
