The computer simulation system of Tongjiezi Hydropower Station has been put into operation for more than 10 years. In order to meet the needs of simulation training, skill identification and skill competition, the functions of the system need to be optimized and upgraded, the operators on duty can master the skills of the actual operation and failure analysis and treatment of the equipment on the spot through the simulation training, to achieve the purposed of "learning for practical use and practicing for proctical use". At the same time, it provides better platform support for hydropower industry skill appraisal and group company skill competition. The system has completed the following functions of research and technological innovation: the improvement of the monitoring system highlight word alarm and bulletin information classification, the dynamic model of secondary voltage of switchyard, auxiliary power and unit, the dynamic model of excitation regulator voltage build-up and step-by-step pressurization, the dynamic model of line and bypass optical fiber protection device in switchyard, the dynamic model of protection device of main auxiliary transformer, the roof drainage control system and drainage dynamic model, the dynamic model of unit speed control system, the dynamic model of pressure channel of unit, and the 66 newly developed and optimized faults handling dynamic models.
