岭澳核电站常规岛部分使用了先进的P32 0分散控制系统作为主要控制手段。P32 0分散控制系统由集中控制层、过程控制层 ;监控网、单元网络、现场总线 ;计算机辅助软件设计工具、计算机辅助软件测试平台等组成。该系统在岭澳核电站常规岛实现保护、逻辑控制、模拟控制和信号处理的功能。通过对P32 0分散控制系统的应用实践发现 ,该系统存在某些不足和缺陷 ,需加以改进和完善 The conventional island section of Ling Ao Nuclear Power Station uses advanced P32 0 decentralized control system as the main control method. P32 0 decentralized control system consists of centralized control layer, process control layer; monitoring network, unit network, field bus; computer-aided software design tools, computer-aided software testing platform. The system functions as a protection, logic control, analog control and signal processing at the conventional island of Ling Ao Nuclear Power Station. Through the application of P32 0 decentralized control system, it is found that the system has some deficiencies and defects, which needs to be improved and perfected
