Field function detection method of portable in-situ bus protection sub-machine

Abstract

The invention relates to a field function detection method of a portable in-situ bus protection sub-machine. A hardware platform of a portable in-situ bus protection sub-machine testing device is used; data communication with a protection debugging platform of a remote debugging center is carried out through a network module port; data of the protection debugging platform of the remote debugging center is utilized, functions to be detected are combined, a test environment under the real operation condition of a transformer substation is simulated for a tested protection sub-machine through various modules, the rapidity and accuracy of protection actions of the protection sub-machine under various fault conditions are tested, on-site automatic testing of the overall function of the tested protection sub-machine is realized, and the workload of parameter setting operation and feedback result comparison by an operator in the conventional on-site testing process is greatly reduced.

Description

technical field [0001] The invention relates to the field of electric power system relay protection, in particular to a field function detection method of a portable in-situ busbar protection sub-machine. Background technique [0002] On-site protection is one of the key development directions of relay protection in the future. The relay protection device does not depend on the merging unit and the intelligent terminal. After the unprotected installation is placed on the ground, the cable adopts cable tripping, which simplifies the intermediate links and can effectively improve the protection. Quickness and reliability. In-situ protection devices mainly include relay protection devices such as line protection, transformer protection, and busbar protection. In order to ensure the independence and reliability of the protection, a dedicated communication network for the protection devices of the whole station is set up, referred to as the protection network for short. Each in...

Problems solved by technology

[0006] Using the above method, although the failure of the on-site operating equipment can be dealt with in time by replacing the on-site equipment, since the equipment must pass the commissioning of the factory commissioning platform of the commissioning center before being replaced on site, the preparatory work for equipment replacement is lengthy, making The replacement work lacks flexibility; for sudden equipment failures on site, it is difficult to effectively deal with equipment failures by means of replacement maintenance because the equipment has not yet been located.

However, the inspection of the equipment running status needs to be completed through the commissioning platform of the commissioning center, and the commissioning platform did not take into account the application scenarios of the equipment operation site when it was designed, making the overall handling work time-consuming and laborious, and it is difficult to meet the requirements of the equipment on-site operation. requirements, which increases the difficulty of equipment fault location, and the rapid location of equipment faults is difficult to achieve
