The Design of Cyber-Physical Simulation Platform for Steam Turbine

Abstract

Steam turbine is the key part of power plant, which is related to the secure and stable operation of generator. With the development of information and communication technology, the steam turbine of power plant has been developed into cyber-physical system (CPS). Existing simulation platforms of steam turbine focus on physical system, which are usually based on single software platform. Since existing simulation platforms simplify communication part of digital electro-hydraulic (DEH) control system, they cannot simulate the scenarios with communication. Therefore, a cyber-physical platform of steam turbine is proposed in this paper, which takes the communication part of DEH control system into account. The physical part of steam turbine is established in Matlab/Simulink, the DEH control system of steam turbine is operated in Beckhoff embedded controller, and cyber part of steam turbine is built by the communication between Matlab and embedded controller with TCP/IP and ads protocol. Finally, the cyber-physical platform of steam turbine is tested under start-up and grid-connected operation conditions to verify its effectiveness and real-time capability. The platform is envisioned as a tool to help steam turbine researchers with the study of relevant problems such as verifying performance of speed control schemes and carrying out cyber security tests of steam turbine.
