IMCS 기반 터빈제어시스템 설계

Generally, the turbine control system of a power plant is a Duplex or TMR (Triple Modular Redundancy) platform, but no control platforms support all of the Single, Duplex and TMR control modes. The IMCS (Integrated Monitoring & Control system) platform of this paper is developed to support not only all of the Single, Duplex and TMR control modes but IEC 61131-3 standard as well, and includes user-defined function blocks for unique turbine control. The turbine control system based on the IMCS platform consists of four parts and the operator environment with HMI, each part is designed to improve availability and reliability - TMR control (TMR mode), common control (Duplex mode), turbine status monitoring (Duplex mode), and protection (TMR mode), and support functions for speed and load control, protection, power system synchronization, diagnostics, etc. In 2012, we will implement this system in the power plant after validation, verification, simulation, and test are performed.
