Turbine governor

Water turbine governor is one of the very important auxiliary control equipment of water turbine generator unit. Its operating quality directly determines the safe and stable operation of the unit. Reducing the failure rate of the turbine governor is the most effective means to improve the operating reliability of the unit.

1. What is a turbine governor

Electricity is one of the important energy sources used in my country’s industrial production and daily life applications. With the ever-decreasing non-renewable resources in my country, the superiority of hydropower is increasingly shown. As an important equipment of a hydropower plant, the governor of a hydroturbine plays a key role in the normal operation of the hydropower station. It is inseparable from the normal power generation of the hydropower station. Once the governor fails, it will directly affect the safety of the turbine and even the power system. Stable operation, therefore, the hydropower plant staff pay attention to the debugging and maintenance of the turbine governor, and timely debugging, overhauling and maintaining the turbine governor can avoid problems with the turbine governor to the greatest extent and ensure the normal operation of the hydropower station.

2. Working principle of turbine governor

The working principle of the hydraulic turbine governor is basically to compare the speed signal (unit frequency) with the grid frequency (given frequency), and give the electro-hydraulic converter a signal (command) to operate the servomotor ON or off according to the difference. The function of controlling the flow of water flowing through the turbine to adjust the speed of the turbine.

3. The role of turbine governor

As an important part of a water turbine, the governor of a water turbine is also a key part of realizing the adjustment of the water turbine. In order to ensure the normal operation of water turbines, and accordingly to ensure the normal and stable operation of hydropower stations, water turbine governors generally have two functions: grid connection function and regulation function. Among them, the grid connection function is an important condition for realizing automatic adjustment of the running state of the turbine. During the normal operation of the turbine, the staff will issue the operating state adjustment instructions to the turbine through the computer, and then the grid-connected function of the turbine governor can automatically adjust the operating state of the turbine according to the relevant instructions, which is beneficial to ensure the stable operation of the turbine. . As the main function of the turbine governor, the adjustment function is also a function that reflects the value of the turbine governor. Its function is to adjust the running speed, water flow, power, etc. of the turbine. That is to say, during the operation of the turbine, the staff can use the adjustment function of the governor to adjust the speed, power, water flow, etc. of the turbine to appropriate values ​​according to their needs, so as to ensure the safety and stability of the turbine operation , And then provide guarantee for the safe and stable operation of hydropower stations.
