Simulation test system of transformer substation training device

Technical Field

The utility model relates to a real simulation test system who instructs device of transformer substation.

Background

With the increasing living standard of urban and rural residents, the power consumption of the urban and rural residents is in an increasing trend year by year, and the construction and maintenance of the transformer substation, especially the intelligent transformer substation, are increasingly important.

With the continuous progress of science and technology, especially the emergence of electromechanical integrated equipment such as electronic transformers and intelligent switches, the development and utilization of modern computer high-speed network technology in real-time systems, the gradual maturity of technologies such as transformer substation operation training simulation and the like, transformer substations enter a new stage of digitization. Automatic monitoring systems have become the most indispensable secondary application system in substation construction. The intelligent transformer substation has irreplaceable effects on the aspects of ensuring the stable, safe and high-quality operation of the transformer substation, and is also an important judgment basis and a guidance tool for operation and maintenance personnel to analyze and process accidents in time.

With the improvement of automation level in a transformer substation, the functions of a transformer substation monitoring system are not limited to monitoring, and basic traditional monitoring functions such as the position state of a primary switch knife switch in the transformer substation, the real-time change of a remote measurement value, the real-time alarm of an alarm window, the prompt and alarm information of an optical character plate, the voice alarm, the remote control of the switch knife switch and the like are achieved. The existing transformer substation operating system also has the functions of telemetering line-crossing alarm, accident recall, telemetering curve drawing, automatic generation of various reports, accident inversion and power failure topology coloring. With the increasing requirement of operators on the intellectualization of monitoring systems, the existing transformer substation monitoring system also comprises an intelligent alarm expert analysis system, an AVQC voltage reactive power automatic regulation system, a CVT current voltage regulation system, a historical alarm system query system and the like.

On the premise that a transformer substation monitoring system is increasingly complex, training of skills of practitioners is increasingly important, the effect of traditional mode training with a brother master is too slow to take effect, and the training is limited by the level of the master, so that the situation that the technical skills of practitioners in different areas are too different is often caused. Therefore, at present, in the electric power and automatic conversation major of each college and universities, an analog simulation mode is often adopted, so that students can quickly learn how to operate and maintain a transformer substation, and the study is not only surface study.
