岭澳核电站LLS003VV调节原理

摘要

LLS system in Ling Ao nuclear power plant plays a very important role in security, in the case of power station lost all auxiliary power, the system can provide the power required to run 9RIS011PO, which first seal of the reactor coolant pump seal water supply, to avoid the leak of reactor coolant, and ensure the integrity of the second barrier. In addition, LLS NSSS also systems, PAMS instrument, master control room, emergency lighting provided with power supply, to ensure the necessary conditions of security control unit. LLS003VV performance has a direct relationship to LLS system's normal operation, and therefore focuses on regulating principle of the LLS003VV described in this article.%LLS系统在岭澳核电站起着非常重要的安全作用，在电站失去全部厂用电源的情况下，该系统能提供9RIS011PO运行所需要的电源，从而给反应堆冷却剂泵的一号轴封供应轴封水，避免了反应堆冷却剂的泄漏，保证了第二道屏障的完整性。此外LLS系统也给NSSS系统、PAMS仪表，主控室应急照明等提供配用电源，以保证一些必要的工况下机组的安全控制。而LLS003VV调节性能的好坏直接关系到LLS系统的正常运行，因此本文着重对LLS003VV的调节原理进行阐述。
