Local-level dispatch supporting system capable of improving analyzing and processing capability of dispatcher during accident generation

Abstract

The invention discloses a local-level dispatch supporting system capable of improving an analyzing and processing capability of a dispatcher during accident generation and belongs to the field of control. The local-level dispatch supporting system is characterized by setting automatic switching device of standby power supply model in an online safety analysis module in a local-level dispatching system; in the scanning of preconceived faults of the online static safety analysis module, 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 in order to accurately reflect a power flow change after the operation of the automatic switching device of the standby power supply, and generating an accident preconceived text based on an analyzed result. When the online static safety analysis module performs N-1 scanning, 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 monitoring intelligent dispatching system used in a district-level 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 to qui...

AI Technical Summary

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
