石壁水库电站改造后已运行二十多年,电站机组设备、自动化控制系统和保护系统、高压配变电等设备及引水发电系统出现老化问题,已不符合电网要求,现如今伴随着一系列问题的出现:如检修不方便、配件难买、运行维护成本高、运行效率低等,已不能满足安全和稳定生产的需要。另外,水库除险加固后,随着水库正常蓄水位的抬高和兴利库容的增加,为保证电站正常、安全运行,为充分利用水能,提高水量利用率,增加发电量的需要,急需全面进行报废重建(增效扩容)。
Shibi Reservoir has been in operation for more than 20 years since it was rebuilt. The aging of power plant equipment, automatic control system and protection system, high voltage distribution transformer and other equipment as well as water diversion and power generation system has not met the requirement of power grid. Nowadays, a series of problems The emergence of: such as inconvenient maintenance, spare parts difficult to buy, high operating and maintenance costs, low operating efficiency, can no longer meet the needs of safe and stable production. In addition, with the reinforcement of reservoirs, with the normal reservoir level rise and the increase of storage capacity, in order to ensure the normal and safe operation of the power station, in order to fully utilize the water energy, increase the water utilization rate and increase the generating capacity, Urgent need for a comprehensive reconstruction of scrap (efficiency expansion).
