On December 17, Anqing 110kV new town power transmission and transformation project officially launched power transmission. When the station is completed and put into operation, it mainly deals with the new residential load power supply of Wuyue square, Anhui land, oasis, central New Town, etc. in Anqing new city, it also supplies dual power supply for residential areas along the way from the east to country garden and the west to Renmin Road, and deals with the problem of peak power supply battery neck, with a direct beneficiary population of about 100000.
110kV new town transformer is located at the south side of the crossing of Huazhong road and planning Ganghua South Road in Anqing city. In this phase, 2 sets of 50MVA three-phase double winding self cooling on load voltage regulating transformers and 3 sets of main transformers with the same capacity are installed in the long-term device; the terminal outgoing line of 110kV outgoing line is planned to be 2 circuits (Quanhe and Longshan). The 10kV outgoing line has 28 circuits in this phase and 42 circuits in the final phase. The total dynamic investment approved is 112.19 million yuan.
The project adopts the 110-a2-4 design plan of China Netcom, which covers a small area. It is a full indoor substation with half a layer of cables. The main transformer adopts the way of separating the main transformer from the radiator. The main transformer adopts the method of fully enclosed noise reduction to effectively deal with the noise pollution of the substation in the urban area.
The completion and operation of 110kV new town transformer will greatly improve the capacity load ratio of 110kV power grid in Anqing City, strengthen the 10kV distribution network structure, improve the power supply reliability, power supply ability and power supply quality of the southern city grid, and effectively reduce the power supply pressure of 110kV East Suburb Transformer and Yicheng transformer.
It is reported that in the construction process of the new town transformation line project, due to the adjustment of urban rail transit planning, the impact of aerial cable into the ground, Wenyuan River and power pipe gallery crossing and stacking, there are many difficulties. With the concern and support of the municipal Party committee and the municipal government, all units participating in the construction of Anqing Power Supply Company of State Grid overcame the unfavorable factors such as rich groundwater, interwoven underground pipelines, and complex construction skill plan, successfully completed the project, and guaranteed the power supply for the peak winter and new year of the power grid.
