An intelligent substation sequence control double confirmation realization method

Abstract

The invention relates to an intelligent substation sequence control double confirmation realization method. The method comprises the steps of firstly configuring a double confirmation condition set ofa primary equipment sequence control operation step and a self-defined logic relation and associating the sequence control task operation step with each other to construct a sequence control servicedata relation; 2 obtaining a sequential operation step of that device, traversing the double confirmation condition set associate with the current step after the pre-operation condition check passes,and recording the real-time state of each confirmation condition; after the step is successfully remotely controlled, obtaining the logic relation of the double confirmation condition bound by the step, extracting and analyzing the dynamic change of each confirmation condition, and judging the overall logic relation to be tenable. The invention adopts the dynamic analysis algorithm to realize thedouble confirmation function of the intelligent substation sequence control, and improves the reliability of the software. The visual user-defined mode is used to configure double confirmation condition set and logic relation, which can flexibly adapt to different requirements of site and users, and improve the universality and ease of use of intelligent substation sequence control software.

Description

technical field [0001] The invention belongs to the technical field of intelligent substations in power systems, and in particular relates to a method for realizing double confirmation of sequence control in intelligent substations. Background technique [0002] In recent years, with the rapid development of power grid construction and the continuous improvement of sequence control technical specifications, sequence control operation technology has become increasingly mature. After the pilot project inspection, it was found that the sequential control operation technology can greatly reduce the workload of switching operations, reduce the risks of misoperation and missed operation, and improve the safety and efficiency of operation, which has great promotion significance.

Problems solved by technology

[0003] However, the smart substation at this stage is constrained by the concept of personnel management. It is believed that the reliability of equipment operation cannot be effectively guaranteed by judging a change in equipment location. In the way of combining gate operation, the system enters the mode of waiting for manual inspection after the sequence control single-step operation is completed, and continues to execute the next step after the manual inspection is passed.

Therefore, the sequential control technology has been greatly restricted in the practical application of smart substations, and cannot reflect the superiority of sequential control operations in smart substations.

How to effectively use the real-time data of smart substations to complete the full inspection of whether the equipment is in place and replace manual inspection has become a major bottleneck in the promotion of smart sequence control technology
