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...

Abstract

The invention discloses an intelligent advanced application system applicable to a local dispatching system, and belongs to the field of control. A spare power automatic switching model is arranged in a dispatcher training simulation system and an online static security analysis module, and an action simulation function for a spare power automatic switching automatic security device is provided. A spare power automatic switching action analysis function is added when the online static security analysis module of the local dispatching system scans expected faults, N-1 scanning after spare power automatic switching action is realized, flow after the spare power automatic switching action is calculated, a dispatcher can independently set the running mode of the spare power automatic switching device when the dispatcher training simulation system or the online static security analysis module is used for N-1 scanning, network power flow distribution in different running modes is simulated and analyzed, so that the dispatcher in a local power network can research safety and stability of a regional power network in real time on line, real-time online power network research safety and stability are improved, an available accident supposition text is generated for the dispatcher, and the power network accident emergency treatment capacity of the dispatcher is improved.

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...
