Problems solved by technology
For example, when a main transformer failure occurs in a substation, the static safety analysis module and DTS cannot correctly simulate the standby and automatic operation of the real power grid, and reasonably calculate the corresponding power flow changes, and at the same time cannot generate a reasonable and usable accident prediction text
In addition, the maintenance function of the standby automatic switching model is not opened in the system, and the dispatcher cannot independently maintain the standby automatic switching operation mode

Embodiment Construction
[0056] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0057] figure 1 Among them, in order to correctly simulate the action of the standby automatic switching device in the static security analysis, it is necessary to formulate the correct standby automatic switching action logic. The action logic of a single standby automatic switching device in the technical solution of the present invention is as follows:
[0058] First, judge whether the main power supply is out of power, if it is out of power, enter the next step of judgment, otherwise end;
[0059] Secondly, judge whether the backup power supply is live, if it is charged, enter the next step of judgment, if it is not charged, all power supplies are effective, and the standby self-switching action is meaningless, so the judgment ends;
[0060] Third, judge whether the current operation mode meets the action requirements of standby automatic switching...

The invention discloses a dispatcher training simulation system with an automatic switching device of standby power supply automatic safety device operation simulating function and belongs to the field of control. The dispatcher training simulation system is characterized by providing an automatic switching device of standby power supply automatic safety device operation simulating function in the dispatcher training simulation system and an online static safety analysis module; in the scanning of preconceived faults in the online static safety analysis module, adding an analyzing function of the operation of the automatic switching device of the standby power supply, achieving N-1 scanning after the operation of the automatic switching device of the standby power supply, computing the power flow after the operation of the automatic switching device of standby power supply and generating an accident preconceived text based on an analyzed result. When the dispatcher training simulation system performs N-1 scanning by using online static safety analysis, a dispatcher may autonomously set the operating mode of the automatic switching device of standby power supply so as to simulate and analyze power grid power flow distribution states in different operating modes, enable the dispatcher to be capable of online researching the safety stability of an regional power grid in real time, improve the safety stability of real-time online power grid research, generate available accident preconceived texts for the dispatcher, and improve a capability of treating emergency power grid accidents for the dispatcher.
Description
technical field [0001] The invention belongs to the field of control, and in particular relates to a power grid dispatcher training simulation system used in a district-level electric power dispatching system. Background technique [0002] With the continuous development of modern power technology, the scale of the power network is getting bigger and bigger, and the complexity is getting higher and higher. [0003] With the increasing impact of regional natural disasters, geological disasters, environmental disasters and external damage on power grid security, higher requirements are put forward for the safe and stable operation of the power grid. The existing power grid monitoring technology cannot fully meet the needs of power grid development. In view of this situation, there is an urgent need to develop a series of practical and operable intelligent advanced applications on the intelligent dispatching technical support system to provide strong support for grid monitors t...
