Intelligent transformation method for ventilation system of underground powerhouse of hydropower station

Abstract

The invention discloses an intelligent transformation method for a ventilation system of an underground powerhouse of a hydropower station. The method comprises the following steps: analyzing system needs according to field actual conditions; establishing a control system and a transmitter in hardware equipment; constructing a lower computer program, developing upper computer software, and performing joint debugging with the hardware equipment; and carrying out joint debugging on the whole set of system, compiling a construction scheme of an online monitoring system, and carrying out field construction and debugging. The method has the characteristics of low cost, complete functions and high automation and intelligence degree, can meet the production and operation requirements of the hydropower station, and is beneficial to the realization of a remote centralized control and few-person maintenance production management mode of the hydropower station.

Description

technical field [0001] The invention relates to the technical field of renovation of the ventilation system of a hydropower station, in particular to an intelligent renovation method for the ventilation system of an underground powerhouse of a hydropower station. Background technique [0002] In recent years, with the sustainable development of my country's economy, my country's hydropower energy development is also in a period of rapid development. At present, my country has built more than 50,000 hydropower stations, including more than 230 large and medium-sized hydropower stations. According to the statistics of the National Energy Administration, as of the end of 2019 , The total installed capacity of hydropower in my country is about 356 million kilowatts, and the annual power generation is about 1.3 trillion kilowatt-hours, accounting for 17.8% of the electricity consumption of the whole society, occupying an important position in the power system. [0003] As an impor...

Problems solved by technology

[0003] As an important hydraulic structure of the power station, the powerhouse of the hydropower station is used to install and accommodate hydraulic turbines, hydroelectric generators and various auxiliary equipment. It is built underground due to geographical conditions and engineering construction needs. The buried depth of underground hydropower stations is generally 100 meters. Above, the building structure is complex, and due to its special function, a large number of main and auxiliary equipment of water turbines are installed inside the factory building, and the underground humid environment and equipment heat dissipation can easily cause the factory building to be stuffy and humid, resulting in the summer temperature of the inner layered room of the factory building being as high as 40°C or higher. , corrosion of mechanical equipment, insulation reduction of electrical equipment, leakage, breakdown and other problems, seriously affecting the safe operation of equipment and the personal safety of staff ； Therefore, it is very important to carry out research on the ventilation of underground power plants, design a good intelligent ventilation system for underground power plants, and regulate the adverse factors such as humidity and heat loads in the plants, which play a very important role in the safe and stable operation of the electromechanical equipment in the plants.
