摘要
近几年,随着国内水电机组装机容量的快速增加,水力电能对电网供电品质的影响愈显突出,因此,对水电厂的智能化要求也随之提高。调速器作为控制水轮机转速和功率的核心设备,其关键装置电液随动系统的智能化程度直接决定了水电机组的供电质量。本文分析了智能电液随动系统的原理及关键技术,提出了实现电液随动系统的智能化与高可靠性的方法。
Recent years,hydro power equipped capacitor increases faster,the hydro power is more important for electric network equality,so the hydro power plant should be more intelligent.The hydro turbine’s frequency and power is controlled by governor,and the governor’s critical part is electro-hydraulic servo system.So the electro-hydraulic servo system’s intelligence plays important role for hydro power equality.This paper analyses intelligent electro-hydraulic servo system’s principle and critical technology,provides one method to realize electro-hydraulic servo system’s intelligent and high reliability.
