Gas - Steam Combined Cycle Power Plant Control Systems And Applications

This paper first analyse the background and meaning of the gas turbine-steam turbine combine cycle power plant come into being, analyse the necessary of control system study and exploitation. To MARK suitable to the actuality of we predominate unredeemed the technique of large gas turbine control, this paper main study and analyse the configuration, Triple Modular Redundancy(TMR), data input output disposal and HMI time synchronization of the control system MARK VI of GE S109FA single shaft combine cycle unit which were quickly set up in the whole china. This paper secondly analyse the DCS control system, main introduce the network structure, control mode, main hardware and software configuration of EMERSON OVATION DCS control system which were largely put into action in the gas turbine-steam turbine combine cycle power plant.This paper bring forward several control scheme of the gas turbine-steam turbine combine cycle power plant, analyse how to come true the control of gas turbine, steam turbine, HRSG, accessorial system and whole combine cycle power plant with MARK VI and OVATION DCS. Bat around the communication design between MARK VI and OVATION DCS, the scheme, work principle and protect function of LS2100 Static Starter, and introduce the EX2100 Excitation system simply.Analyse the inducement of ubiquitous failure of communication between MARK VI and OVATION DCS and give a doable settle scheme, it may be helpful to settle the similar failure for domestic S109FA combine cycle power plant. Analyse and discuss some questions about Static Starter and Excitation system in power plant debugging and running.
