Design and Application of Large-CapacityKaplan-Type Turbine Governor

Abstract

随着社会对可持续发展和节能减排的日益重视,水电已成为优先发展的清洁能源,大容量轴流转桨式机组在水电建设中已得到普遍采用,但其调速系统的控制机理复杂,安全性与可靠性要求较高。 本文在可编程计算机控制器(PCC)的基础上对该类机型的调速器进行了研究和设计,并对现场应用及试验情况进行了详细介绍。 针对轴流机组控制复杂的特点及当前调速器测频的精度和可靠性不高的缺点,通过对比分析,采用高可靠性的PCC模块作为机组调速器的硬件,并设计了PCC调速器的电气控制系统结构,阐述了频率测量的原理及实现方法。 本文对调速器采用的PID控制算法进行了研究,分析了对积分环节以及调差的反馈信号所取位置进行改进之后的...With increasing emphasis on sustainable development and energy conservation of society, Hydropower has become a priority to the development of clean energy Large-capacity Kaplan-type turbine in hydropower construction has been universally adopted. The mechanism of control of the Governor system is complex and also it has high safety and reliability requirements. The research and design has been ...学位:工程硕士院系专业:软件学院_工程硕士(软件工程)学号:X201023018
