新春走基层丨四川：走，给水电机组做“体检”

Core Viewpoint - The article highlights the operational status and maintenance of the Yinjiang Hydropower Station, emphasizing its significance in the Sichuan hydropower sector and the advancements in technology used in the facility [3][4]. Group 1: Hydropower Station Overview - The Yinjiang Hydropower Station has successfully integrated all six units into the grid, contributing to Sichuan's total hydropower installed capacity exceeding 100 million kilowatts [3]. - The station utilizes bulb-type turbine generators, which are designed to maximize the advantages of high inflow, with the largest single unit capacity in Asia and a turbine diameter of 7.95 meters [3]. Group 2: Maintenance and Performance Testing - Routine maintenance, referred to as a "health check," is conducted on the generator units to ensure optimal performance, with the first unit undergoing testing after a year of operation [4]. - The testing process involves applying increasing voltage levels to the generator's stator, confirming that the insulation performance remains within acceptable limits, indicating the generator is in excellent working condition [4]. Group 3: Future Plans and Efficiency Improvements - The company aims to complete the dismantling of downstream cofferdams before the Spring Festival, allowing the hydropower station to reach a reservoir level of 998.5 meters [5]. - Efforts are being made to optimize the operational plans for the generator units to enhance efficiency and maximize electricity generation from the available water flow [5].
