Abstract
In order to solve the problem of automatic evaluation of dispatcher fault simulation training in distribution network, a simulation training evaluation method based on radar chart for distribution network fault is proposed. The fault handling information matrix is established to record the dispatcher fault handling operation sequence and operation information. The four situations of the dispatcher fault isolation operation are analyzed. The fault handling anti-misoperation rule set is established to describe the rules prohibiting dispatcher operation. Based on the idea of artificial intelligence reasoning, the feasibility of dispatcher fault handling is described by the feasibility index. The relevant factors and evaluation methods are discussed from the three aspects of the fault handling result feasibility, the anti-misoperation correctness and the operation process conciseness. The detailed calculation formula is given. Combining the independence and correlation between the three evaluation angles, a comprehensive evaluation method of distribution network fault simulation training based on radar chart is proposed. The method can comprehensively reflect the fault handling process of dispatchers, and comprehensively evaluate the fault handling process from various angles, which has good practical value.
Highlights
With economic development, people's demand for reliability of power supply continues to increase
It is of great significance to study a simulation training evaluation method for distribution network fault, which can tolerate dispatcher isolation and transfer to non-standard operation, and can effectively reflect dispatcher training operation and business level
Based on the characteristics of the simulation training of distribution network fault, this paper presents a comprehensive evaluation method of distribution network fault simulation based on radar chart from the three dimensions of the fault handling result feasibility, the anti-misoperation correctness and the operation process conciseness
Summary
People's demand for reliability of power supply continues to increase. The reference [9] proposed a man-machine combined intelligent evaluation method of substation simulation This method has great improvement in fault-tolerant case, but requires human intervention to correct the result. The reference [10] proposed a substation simulation training method based on the combination of expert system and weight function This method introduced expert mechanism and weighting function, but did not describe fault tolerance and fuzziness of dispatcher operation. The reference [13] proposed a method of transformer substation operation training evaluation based on the principle of maximum matching. It is of great significance to study a simulation training evaluation method for distribution network fault, which can tolerate dispatcher isolation and transfer to non-standard operation, and can effectively reflect dispatcher training operation and business level. The seventh column is the feeder ID of the equipment, and the loop-switch belongs to the two feeder lines associated with it. m is the dispatcher fault handling steps
