Design and Development of Virtual TXP Control System Software

Taking distributed control system（DCS） of Siemens TELEPERM_XP（TXP） as the simulation object,Virtual TXP（VTXP） control system based on Virtual DCS with high fidelity and reliability was designed and developed on the platform of Windows.In the process of development,the method of object-oriented modeling and modularization program design are adopted,C++ language and technologies such as multithreading,ActiveX control,Socket network communication are used,to realize the wide range dynamic simulation and recreate the functions of the hardware and software of real TXP.This paper puts emphasis on the design and realization of Control server and Communication server.The development of Virtual TXP control system software is with great effect on the construction of simulation system and the design,commission,verification and maintenance of control system in large-scale power plants,nuclear power plants and combined cycle power plants.
