A method for comprehensive monitoring of multi-dimensional status of distribution automation terminals

Abstract

The invention discloses a distribution automation terminal multi-dimensional state integrated monitoring method. With the help of a self-diagnosis function of a device itself, element-level, board-level and device-level multi-dimensional state online monitoring on the terminal device is realized. The method comprises online monitoring on a key hardware state of the distribution terminal, online monitoring on the distribution automation DC power supply state and online monitoring on a secondary loop of the distribution terminal. The method solves the problems of blind detection and insufficient maintenance on the terminal device caused by regular maintenance, the passed blind regular detection is changed to scientific maintenance for maintenance of the terminal device, the pertinence, the rationality and the operation maintenance efficiency for device maintenance are improved, and the operation maintenance cost is reduced.

Description

technical field [0001] The invention relates to a multi-dimensional state comprehensive monitoring method of a power distribution automation terminal, which belongs to the field of power systems and automation thereof. Background technique [0002] With the progress of my country's electric power industry and the rapid development of smart grid construction in recent years, the traditional scheduled maintenance system for equipment is no longer suitable for new requirements, and the weaknesses of lack of pertinence and lack of scientific basis are gradually exposed. The defects found in the equipment during the maintenance play a role in ensuring the safe and economical operation of the equipment, but the regular maintenance has the defects of blind maintenance and insufficient maintenance. Some well-run equipment was forced to stop for maintenance when it expired, resulting in blind maintenance of some equipment, resulting in a lot of waste of manpower and material resources...

AI Technical Summary

Problems solved by technology

[0004] In recent years, with the rapid expansion of distribution automation scale, the development of distribution automation terminal operation and maintenance management technology has lagged behind.

At present, the terminal operation and maintenance still adopts two methods of fault inspection and regular inspection. These two methods are either simple replacement inspection, which directly replaces the faulty equipment without repairing it, which is costly, or regular on-site maintenance that consumes manpower and material resources. Maintenance, resulting in high operation and maintenance costs

The operation and maintenance automation of the distribution automation system is low, and the information obtained by the operation and maintenance personnel is messy, and it is impossible to accurately find the root cause of the problem and solve it in time, which reduces the operation and maintenance speed of the distribution network terminal

In particular, the large number of distribution automation terminals and the complex operation and maintenance environment have increased the difficulty of related operation and maintenance work, and have also become an important factor restricting the improvement of the practical level of distribution automation systems.
