Tender Announcement for the Reconstruction and Construction Project of 110kV High Voltage Power Distribution Device and Auxiliary Equipment of Hongyanzi Hydropower Plant of Hongyanzi Electric Power Co., Ltd. in Southern Sichuan Province

Information
Hongyanzi Electric Power Co., Ltd. in southern Sichuan Province (hereinafter referred to as Hongdian Company) intends to open a tender for the 110kV high-voltage power distribution device and its auxiliary equipment installation project of Hongyanzi Hydropower Plant (tender number: HYZ-GC-20-028) , Welcome potential bidders who meet the qualification requirements of Article 4 of this Tender Announcement to bid on this project.
 
 
 
1. Project Overview
 
Overview
 
Hongyanzi Power Plant is located in the middle section of Binjiang Road in the southern county of the middle reaches of the Jialing River. Construction started in October 1997. The first unit was put into operation in 2001, and all three units were put into operation in 2002. It is the fourth-level electrical and aviation project in the cascade development plan of the Jialing River from Cangxi, Sichuan to Hechuan, Chongqing approved by the state. It focuses on power generation and integrates electricity and navigation. The total investment is more than 900 million yuan. , With an installed capacity of 3×30MW bulb tubular units, with an annual design generating capacity of 425 million kilowatt-hours.
 
The power plant has a 110kV switch tower, which is arranged in layers, and the 110kV high-voltage power distribution device is single-bus section wiring.
 
 
The existing 110kV high-voltage power distribution device is a single bus (tube type bus) is connected in sections. The 110kV switch room has two inlet intervals for the high-voltage side of the main transformer, four outlet intervals for the lines (two spare and two in operation), and one bus tie interval. There are two busbars PT on the 110kV outlet layer.
 
 
The 110kV high-voltage power distribution device is an open-type power distribution device, which is an outdoor power distribution device installed indoors. It has been in operation for nearly 20 years. The equipment is aging and close to the service life; the model is old and the failure rate is high; some of the equipment and conductors are corroded There are signs that the cost of overhaul and maintenance has increased, the insulation strength has decreased, the stability and reliability of equipment operation has decreased, and the energy consumption of the equipment itself has increased, posing potential hazards to the normal operation of power plants. Therefore, all of them need to be replaced to meet the requirements of the current regulations.
