Problems solved by technology

In the dispatcher training simulation in the prior art, the evaluation index does not evaluate the rationality of the equipment recovery operation after the power grid failure, that is, the recovery sequence of the recoverable equipment is not evaluated, but the operation sequence of the recoverable equipment is directly Affecting the safe and stable operation and power supply economy of the power grid restoration process after the fault, the reasonable planning of the power grid operation process is the skill that the power grid dispatcher must have

Abstract

The invention discloses a post-fault recoverable equipment operation sequence evaluation method, device and system, and the method comprises the steps: obtaining an anticipated power grid model whichis built based on the complete disconnection of all switching-on and switching-off equipment in a to-be-recovered power grid after a fault in a pre-fault power grid model; calculating a power grid risk probability corresponding to each recoverable device in the anticipated power grid model; sorting all the calculated power grid risk probabilities to obtain a recovery sequence of each recoverable device; and calculating a real-time evaluation score of the operation condition of the dispatcher based on the recovery sequence of each recoverable device and the sequence of the devices actually operated by the dispatcher in all the recoverable devices, and completing the evaluation of the operation sequence of the recoverable devices. According to the method, the optimal recovery sequence of therecoverable equipment of the power grid after the failure is analyzed and calculated, and then the actual operation result of the dispatcher is evaluated based on the calculated optimal recovery sequence, so that the effective evaluation of the operation rationality of the power grid after the failure of the dispatcher is realized.

Description

technical field [0001] The invention belongs to the field of power system simulation training, and in particular relates to a method for evaluating the operation sequence of recoverable equipment after failure. Background technique [0002] With the rapid construction of smart grid and UHV power grid, the physical form and operating characteristics of the power grid have changed significantly, and the characteristics of the power grid have shifted from a regional model to an overall model. Power grid dispatchers grasp the operating characteristics of UHV power grids, improve the ability and quality to control the safe and stable operation of UHV power grids, and effectively avoid major power grid accidents. Scheduling simulation training is an effective way to improve the skill level of dispatchers, and the scientific and accurate evaluation of trainees' behavior can guide trainees to find their own weak points in a targeted manner, and then improve the dispatching skills ac...
