Abstract

The invention discloses a control logic verification platform for a million-capacity-grade turbine island, and relates to the field of turbine control. The invention aims at solving the problems thata command sent by an existing turbine island control system cannot be fed back, the correctness of the control logic cannot be verified, and the control logic cannot automatically execute the next sequential control step. A simulation unit is used for constructing a turbine auxiliary system and a turbine body simulation model, receiving a control signal and executing a control command, and feedingcurrent state information of the simulation model back to a distributed processing unit; the distributed processing unit is used for receiving a control signal of a man-machine interface station, andstarting the simulation model according to a set starting program in order to make the turbine auxiliary system and the turbine body simulation model carry out operation control in sequence; and theman-machine interface station is used for inputting the control signal to the distributed processing unit, and is further used for displaying state information and comparing the feedback state information with the input control signal. The control logic verification platform is used for verifying the control logic of the turbine island.

Description

technical field [0001] The invention relates to a control logic verification platform of a steam turbine island with a capacity of one million. It belongs to the field of steam turbine control. Background technique [0002] The mega-capacity steam turbine system has a complex structure and variable operation modes. The steam turbine body plays a vital role in the safe and stable operation of the unit. [0003] After the design and development of the steam turbine body is completed and before the unit is started, there is no control object, and the commands issued by the steam turbine island control system (steam turbine body and steam turbine auxiliary system) cannot be fed back, and the correctness of its control logic cannot be verified, and the control logic cannot be automatically executed. The next sequential control step. Contents of the invention [0004] The invention aims to solve the problems that the commands issued by the existing steam turbine island contro...
