摘要
分析了使用光电传感器和发电机电压测量水轮机频率时各自的利弊,提出了采用优势互补的混合方式进行测量,介绍了该方式的原则及实现方法,以及加强可靠性的若干措施.实验表明该方法是有效的.
This paper analyses the respective advantages and disadvantages of the two methods of using photoelectricity sensors and generating voltage to measure the frequency of a hydroturbine and also proposes a combined measu ring method with the advantages of the two methods. The principle and implementation of the method are introduced,together with several means to strengthen its reliability.
