摘要近年来，我国的水电建设取得了突飞猛进的发展。然而，因为发电过程中水轮机的负荷在不断发生变化，使其转速也随之变化，导致输出的电压和频率的不稳不能满足用户的需要。因为发电机的输出频率是随着转速变化而变化，所以为了满足水轮发电机组并网输电频率指标要求，就需要对水轮发电机组进行速度控制。速度调节器在水轮发电机组并网发电系统中是一个核心控制单元，它通过对液压驱动装置一接力器的行程控制，实时对水轮机导叶开度的调节，达到对水力矩大小的调节，从而实现对水轮机组转速的控制使它保持在一定的范围内，最终实现电压和频率的稳定输出。

本文设计了水轮机调节系统的控制原理，进而对水轮机调节系统包括的PID控制算法、电机伺服系统、水轮机组、测量电路等进行计与仿真从而为提升水力发电的控制和今后进一步对调节系统进行更为深入的供参考与借鉴。78204

Design and Simulation for Hydraulic Turbine Governor

Abstract Recently, China's hydropower construction has made rapid development。 However, with the process of power generation turbine load constantly changing, it also changes speed, causing the output voltage and frequency instability can not meet the needs of users。 The output frequency of the generator with the speed variation and changes, so in order to meet the group and Hydro transmission grid frequency target, we need to control the speed of the turbine generator set。 The speed controller is set in hydroelectric power generation system in a central control unit, which by a stroke of the hydraulic drive apparatus servomotor control, real-time adjustment of the turbine guide vane opening, to adjust the size of the water moments, in order to achieve hydraulic turbine speed control to keep it within a certain range, and ultimately stabilize the output voltage and frequency。

The principles of the turbine control system are described in this paper。And then the hydraulic turbine regulating system is adjusted including a PID control algorithm, servo system, hydraulic turbine, measuring circuit, etc。 are counted and simulation so as to enhance the control and hydroelectric power in the future to further adjust the system for others for in-depth information and reference。
