海南核电站在大机小网中运行安全的研究和实践

Study and Practice of Operation Safety of Hainan Nuclear Power Plant in a Small Grid

由于电网负荷需求、增长和总量达不到预期,电网的调峰能力不足以及电网事故考核等因素,为确保厂网安全,海南核电被迫长期降负荷运行。本文分析了核电长期降负荷运行一些关键影响因素,开展了长期低功率运行专题研究和实践应用,提出核电长期降负荷运行的对策,为核电机组在中小电网营运提供参考借鉴。

Due to the grid load demand,the growth and gross of the grid capacity unable to meet expectations,insufficient peak load regulation capacity,and power grid accident assessment,Hainan Nuclear Power Plant was forced to a long-term below rate-power operation to ensure the safety of both the plant and the power grid.In this paper,related key impact elements for long-term below rate-power operation,studies,results and practical applications in this regard are analyzed,and countermeasures for long-term below rate-power operation are put forward.The valuable results could be referred to for nuclear power plants operated in a similar environment.
