Description

Pool guardrail of a pumped storage power station

technical field

The utility model belongs to a guardrail, in particular to a pool guardrail of a pumped storage power station.

Background technique

The production, transmission, and use of electricity occur simultaneously and generally cannot be stored, while the demand for electricity loads changes rapidly. Within a day, the electricity demand is higher during the day and the first half of the night; it drops sharply in the second half of the night, and the trough is sometimes only half of the peak or even less. In view of this situation, power generation equipment must be fully powered during peak load hours, and must be lowered or even temporarily shut down during low-peak hours. In order to coordinate the use of relevant power generation equipment according to power demand, a series of measures need to be taken.

With the rapid development of the national economy, the scale of the power grid is getting larger and larger, and the role and status of the pumped storage power station in the power grid are becoming more and more significant. The tool has been highly valued by the hydropower construction department and operation management agency. Pumped storage power station is a special power station with fast start, fast load tracking and fast response.

The pumped storage power station was created to solve the contradiction between supply and demand between the peak and trough of the power grid, and it is a way of indirect storage of electric energy. It uses the excess power in the second half of the night to drive the water pump to pump water from the lower reservoir to the upper reservoir for storage, and then releases the water to generate electricity during the day and the first half of the next day, and flows into the lower reservoir. During the whole operation process, although part of the energy will be lost during conversion, in comparison, the use of pumped storage power stations is still better than the situation of adding coal-fired power generation equipment to meet the peak power consumption and load and shut down during the low valley. Come cheap, benefit better. In addition, the pumped storage power station can also undertake dynamic functions such as frequency modulation, phase modulation and emergency backup. Therefore, the pumped storage power station is not only a power source, but also a power user; it has become an important tool for the operation and management of the power grid, and is the pillar to ensure the safety, economy and stable production of the power grid. The pumped storage power station has two main operation modes of power generation and pumping water, and there are many operations from one working condition to another between the two operating modes.

The components of the pumped storage power station mainly include: (1) upper reservoir, (2) water delivery system, (3) plant, (4) switching station and outlet field and (5) lower reservoir. The plant includes main and auxiliary plant buildings, main transformer tunnel, busbar tunnel and other caverns. The upper reservoir of the pumped storage power station is an engineering facility for storing water. During the low load period of the power grid, the pumped water can be stored in the reservoir, and the reservoir can be released to generate electricity during the peak load period. The water delivery system is an engineering facility for transporting water. In the working condition of the water pump (pumping), the water from the lower reservoir is delivered to the upper reservoir, and in the working condition of the turbine (power generation), the water released from the upper reservoir is delivered to the lower reservoir through the factory building. Therefore, it is necessary to pay attention to the water level of the upper reservoir reservoir. During night inspections, because the existing guardrails are generally made of metal, when the staff use flashlights to illuminate, it is prone to dazzling phenomenon; the reservoir is slippery, and in the dark Walking is slow, and in case of emergency, it is easy to cause personal injury; at the same time, due to the unique environmental characteristics of the reservoir, the existing guardrails are prone to rust and corrosion, and their service life is low.
