Since most of the power generation of the hydropower station is completed by operating the hydropower unit, if there is a problem or fault, the hydropower unit is easy to seriously affect the power generation of the hydropower station. Due to the long operation time of hydro generator, the fault is imminent. In order to minimize a series of losses caused by such faults, relevant technicians shall identify and clarify common faults, inspect and maintain these faults and problems, and effectively improve the safety and stability of hydraulic units.展开更多

In order to protect the environment and take the path of green development, it is necessary to change the source of energy. Hydropower is favored by people with its advantages of environmental protection. The wide application of hydropower also promotes the increasing number of hydropower stations. The number of hydropower stations in China is large, but the service time of hydropower stations is relatively short, and there are still some problems in many aspects. Governor is an indispensable device for hydropower generation, which plays an irreplaceable role in hydropower generation. Once there is a problem with the governor of hydropower station, it will affect the whole power station. In order to reduce the impact of the governor failure of hydropower station, we must analyze the common faults of the governor of hydropower station, and prepare the corresponding maintenance plan for these common faults, which can be repaired quickly in case of failure, so as to minimize the impact on the hydropower station as far as possible. This paper briefly analyzes the common faults and maintenance methods of the governor of hydropower station.展开更多

Whether it is the safety needs of the whole production process or in the operation process, it is required to make clear that the use effect of the system is constantly improving, which can reduce the frequency of problems and truly meet the relevant needs of the current industrial enterprise development. Therefore, we should analyze how to maintain the chemical instrument automation equipment in the process of operation, and find the relevant measures to solve the problem.展开更多

As a vital node facility of the power system, 110kV substation needs to adjust the management strategy in combination with the daily operation and maintenance of the substation. However, in the current substation management, there is a general concern about management risks inadequate consideration of technical risks and external operation and maintenance risks has seriously affected the stability of power system and power quality. Targeted preventive measures should be taken to improve the operation and maintenance capacity of 110kV substation.展开更多
