核电厂反应堆保护系统故障检测设计

Fault Detection Design for Reactor Protection System of Hainan Changjiang Nuclear Power Station

反应堆保护系统是核电厂仪控系统的核心部分。为探测保护系统设备的故障,验证系统的可用性,确保核电厂的安全,需对保护系统进行定期故障检测。本文介绍了基于Tricon V10可编程逻辑控制器(PLC)系统的海南昌江核电厂反应堆保护系统故障检测设计以及故障检测的范围与功能,并对其特点进行了分析。

Reactor protection system is a key part of instrument and control system in nuclear power plants. In order to detect the fault of the protection system equipment, validate the availability and assure the nuclear power plant safety, the periodic fault detection shall be applied. This paper introduces the fault detection design, scope and function of the reactor protection system in Hainan Changjiang nuclear power plant based on Tricon VIO programmable logic controller （PLC）, and also analyzes the characteristics of fault detection.
