滨海电厂循环水泵消波研究

Research on Wave Damping of Circulating Water Pump in Coastal Power Plants

针对滨海电厂波浪对循环水泵安全运行的影响及消波的重要性进行了分析,结合浙江某发电厂的工程实例,计算和分析了循环水泵进水流道几种有效消波措施,并进行了技术经济比较。选取进水前池内短暗沟消波方案进行了物理模型试验验证和优化,设计采用了能确保循环水泵安全运行且简单易行的18 m短暗沟消波方案,以达到循环水泵稳定运行的目的。

The paper analyzes impact of waves on safe operation of the circulating water pump in coastal power plants and the importance of wave damping. Combining with a power plant project in Zhejiang, the pa- per calculates and analyzes several effective measures of wave damping in inlet channel of circulating water pump and compares their technical and economic efficiency. The wave damping scheme for short blind ditch in the front pool is verified and optimized by physical model test. The simple and feasible wave damping scheme for eighteen-meter short blind ditch that can ensure operation safety of circulating water pump is adopted to make sure the pump can operate stably.
