What is the substation commissioning unit?

Hello, a substation commissioning unit is an institution or company specializing in the commissioning of substations. After the construction of the substation is completed, debugging work is required to ensure the normal operation and safety of the substation. Debugging work includes equipment inspection, testing, adjustment and testing, etc., and requires certain skills and experience. The substation debugging unit usually consists of a group of experienced electrical engineers and technicians. They have rich practical experience and professional knowledge and can carry out reasonable debugging and testing of various equipment. At the same time, they must also master relevant electrical standards and specifications to ensure that the debugging work complies with safety regulations and quality requirements. The betting unitin substation service has a wide range of works, involving various high voltage equipment, switching equipment, protective equipment and monitoring systems, etc., which require detailed inspection and testing of various equipment. In the process of substation construction, the substation commissioning unit plays a vital role. His work is directly related to the operational efficiency and safety of the substation and therefore requires great attention.

Dahuashui Reservoir is located in Kaiyang County, Guizhou City, Guizhou Province.

Reservoirs are divided into state-owned reservoirs and reservoirs collectively managed by townships (cities) and villages. The daily management of state-owned reservoirs is carried out by the Water Conservancy Technical Management Bureau, which is under the local water administration department.

Dahuashui is the third level of the cascade development plan. The development of Qingshui River cascade hydropower is Wujiang Company's first attempt to invest in small and medium-sized hydropower in Guizhou through diversification. The investors are Wujiang Company, Guizhou Tengyuan Electric Power Development Co., Ltd., Guiyang Survey and Design Institute, Guizhou Qianneng Tianhe. Mining Co., Ltd., Kaiyang County.

The Dahuashui Hydroelectric Power Station Dam (parabolic hyperbolic arch dam + left bank gravity dam) is located in an alpine canyon area. The mountain walls on both sides of the dam site are steep, making concrete placement difficult. silos. According to the unique ground conditions of the project, three negative pressure slides were arranged on the left bank slope of the gravity dam in two phases, that is, the lower lineof the first phase used an 800 mm wide conveyor belt and two negative pressure slides. ; the upper line of the second phase used A 1000 mm wide belt conveyor and a negative pressure chute are installed; The concrete from the arch dam is mainly placed in storage using a slowdown chute (due to the steep slopes on both sides of the chute). arch dam, with an average angle of 70°, an ordinary negative pressure chute cannot be used to transport roller compacted concrete on such high and steep slopes). Using slow falling chute pipes to transport roller compacted concrete not only guarantees the quality, but is also superior to negative pressure chute pipes in terms of transportation strength, installation period, installation costs. installation and operation, etc., thus laying the foundation for rapid construction. of arch dams.

Dahuashui Hydropower Station is located at the junction of Kaiyang County and Fuquan City in Guizhou Province, in the canyon section of the middle reaches of the Qingshui River. This is the third level of the main hydropower of the Qingshui River. development. The power plant has a total installed capacity of 200 MW and a total investment of 1.4 billion yuan. The dam is a parabolic hyperbolic arch dam + gravity pier and the right bank is a hyperbolic arch dam. The total length of the dam axis is 287.56 meters. The thickness/height ratio is 0.171. It is the tallest hyperbolic arch dam under construction in China. The dam body is equipped with two flood discharge holes and three overflows. A surface hole, a water collection well and a suspended well are also arranged downstream of the arch dam. Two induced joints are placed in the hornps of the dam, and short peripheral joints are placed on both sides. The body of the arch dam is high and presents a complex. body morphology.
