摘要
近年来,随着可再生能源规模不断提高,电力系统面临高比例消纳、稳定性可靠性等关键问题,抽水蓄能作为目前最可靠最清洁的储能方式其作用日益凸显。抽水蓄能电站励磁系统作为同步电机的核心组成部分,励磁系统的响应速度与稳定性对电力系统的安全至关重要。本文分析了励磁系统的结构、控制逻辑以及软起励和自动升压两种起励方式,通过对比可知两种起励方式下的机端电压上升平稳,均满足标准要求,但自动升压方式在响应速度上明显快于软起励方式,更有利于电网快速调节,发挥抽水蓄能"蓄电池""调节器""稳压器"的作用。
In recent years,with the continuous increase in the renewable energy,the power system is facing critical challenges about high proportion of consumption and its stability and reliability.At present,pumped storage has become increasingly prominent as the most reliable and clean energy storage solution.Excitation system of pumped storage power station is the core component of synchronous motor.The response time and stability of excitation system are important to system's safety.This paper analyzes the structure,control logic,and two excitation methods—soft excitation and automatic boost—of the excitation system.Comparative analysis reveals that the terminal voltage rises steadily under both excitation methods,meeting the standard requirements.However,the automatic boost method has a significantly faster response time than the soft excitation method,which is more conducive to rapid grid adjustment and enhances the role of pumped storage as a“battery,”“regulator,”and“voltage stabilizer.”
