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 drawings and embodiments.

[0057] figure 1 In order to correctly simulate the action of the standby automatic switching device in the static safety analysis, it is necessary to formulate the correct standby automatic switching operation logic. The action logic of a single standby automatic switching device in the technical scheme 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, go to the next step, otherwise end;

[0059] Secondly, judge whether the standby power supply is live, if it is live, go to the next step of judgment, if it is not live, then all the power supplies are effective, the automatic switching action is meaningless, and the judgment ends;

[0060] Third, determine whether the current operation mode meets the action requirements of the standby automatic input, and the operation mode needs to be set in th...

Abstract

The invention relates to an online static safety analysis system applicable to a ground survey system, which belongs to a control system. It includes an online static security analysis module, in which a standby self-switching model is set, and in the online static security analysis module scanning for expected faults, the analysis function of the standby automatic switching action is added to realize the standby automatic switching action. The N-1 scan of the N-1 scan calculates the power flow after the automatic switch-on action of the equipment, and generates an accident prediction text based on the analysis results; when using the online static safety analysis module to perform the N-1 scan, the dispatcher can independently set the equipment The operation mode of the self-injection device is used to simulate and analyze the power flow distribution of the power grid under different operation modes, so that the dispatcher can conduct real-time online research on the safety and stability of the regional power grid, and improve the real-time online research on the safety and stability of the power grid. And generate available accident prediction texts for dispatchers, so as to improve the dispatcher's emergency response ability for power grid accidents.

Description

Technical field [0001] The invention belongs to the field of control, and in particular relates to an online static safety analysis system for a regional power dispatch system. Background technique [0002] With the continuous development of modern power technology, the scale and complexity of power networks are getting larger and larger. [0003] As the regional natural disasters, geological disasters, environmental disasters, and external force damage have greater and greater impact on the security of the power grid, higher requirements are put forward for the safe and stable operation of the power grid, and the existing power grid monitoring technology methods cannot fully meet the needs of power grid development. In view of this situation, there is an urgent need to develop a series of intelligent advanced applications with both practicality and operability on the intelligent dispatching technical support system to provide strong support for grid supervisors to quickly deal wit...
