灯泡贯流式水轮发电机组由于贯性时间常数小、水流时间常数大,空载、小网运行不稳定、甩负荷转速过高或过低,是灯泡贯流式水轮发电机组普遍存在的问题。但是,1998年8月,桂平航运枢纽水电厂用武汉三联公司的 PLC 微机调速器提供的硬环境,通过 PID 参数的适当调整,控制程序的恰当设计后,取得了可喜的效果,基本上解决了困扰贯流式水轮发电机组运行不稳定、甩负荷过速的问题。 Bulb turbine generator set due to the consistency of small time constant, large current constant time, no-load, small network instability, rejection load speed is too high or too low, is the bulb tubular turbine units ubiquitous problem. However, in August 1998, the hard environment provided by the PLC microcomputer governor of the Wuhan Triple Company in the Guiping Navigation Hub Hydropower Plant achieved satisfactory results after properly adjusting the PID parameters and controlling the program, and basically solved the problem Turmoil plagued tubular turbine instability, load shedding speed problems.
