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].

Core Viewpoint - The article highlights the operational status and maintenance of the Silver River Hydropower Station in Sichuan, emphasizing its significance in the regional hydropower landscape and the technological advancements in its turbine design. Group 1: Company Operations - The Silver River Hydropower Station has successfully integrated all six units into the grid, marking a significant milestone for Sichuan's hydropower capacity, which has now surpassed 100 million kilowatts [2][3]. - The first unit of the hydropower station began generating electricity in December 2024, with the last unit coming online in December of the previous year [2]. Group 2: Technological Advancements - The hydropower station utilizes bulb-type turbines, which are designed to maximize the advantages of high flow rates, with the largest single unit capacity in Asia and a turbine diameter of 7.95 meters [2][3]. - The maintenance process includes preventive testing of the generator's stator and rotor, confirming that the insulation performance is within acceptable limits after one year of operation [3]. Group 3: Future Plans - The company aims to complete the dismantling of the downstream cofferdam by the Spring Festival, allowing the hydropower station to gradually reach a water storage level of 998.5 meters [3].
