Background
The problem of monitoring the electrical secondary circuit is that at present, because of the micromachine of the protection device, the state monitoring is easy to realize. However, the secondary electrical circuit is composed of a plurality of relays and cables connecting the devices, and has many and scattered points, so that it is difficult to monitor the conditions of relay contacts and the correctness of circuit wiring on line, and it is not economical. The electrical secondary circuit is mainly started from equipment management methods, such as equipment acceptance management, offline maintenance data management and online monitoring, so as to diagnose the state of the equipment.
The electromagnetic anti-interference monitoring problem of secondary equipment of an electric power system is that the secondary equipment is more and more sensitive to electromagnetic interference and is extremely easy to be subjected to the electromagnetic interference due to the wide application of a large number of microelectronic elements and highly integrated circuits in the secondary equipment. The interference of electromagnetic waves on secondary equipment causes the distortion of sampling signals, the abnormality of automatic devices, the protection misoperation or the rejection, and even the damage of elements. The international electrotechnical commission and the domestic related departments set up electromagnetic compatibility standards for relay protection.
However, at present, monitoring and management of the field electromagnetic environment are not brought into the overhaul range, and a proper monitoring means is not provided, an electromagnetic compatibility examination test on secondary equipment is a very important work for secondary equipment state overhaul, and monitoring and management on interference sources, coupling paths and sensitive devices of different stations are required, such as secondary equipment shielding grounding condition examination, management of mobile communication equipment used near a microcomputer protection device and the like.
The condition of the secondary equipment is overhauled and the condition of the primary equipment is overhauled, the primary equipment is overhauled and the secondary equipment is overhauled not completely independently, and the secondary equipment is overhauled only when the primary equipment is overhauled in a power failure mode under many conditions. When making a secondary equipment state maintenance decision, the condition of primary equipment needs to be considered, the economic analysis of state maintenance technology is made, the power failure maintenance time is shortened, the economic loss caused by power failure (power supply) is reduced, the maintenance times are reduced, the maintenance cost is reduced, and the reliable and correct work of secondary equipment is ensured.
The relationship between the maintenance of the secondary equipment state and the equipment management information system is established in many stations, and computer management and information sharing are realized on the running condition, the defect fault condition, the previous maintenance test record and the like of the equipment, and the information is one of important bases for making a state maintenance decision. To implement the condition maintenance of the secondary equipment, the condition maintenance equipment management information system of the secondary equipment needs to be perfected.
The state maintenance of the electric secondary equipment is the development requirement of the electric power system, and along with the wide use of microcomputer protection and self-diagnosis technology of microcomputer automatic devices, the state monitoring of the electric secondary equipment is easy to realize technically and economically. With the development of an integrated automation system, the number of secondary equipment and cables can be greatly reduced, and the difficulty of conventional protection state monitoring at present is overcome.
The equipment management information system is widely used in the power system, provides information support for the condition maintenance of the electrical secondary equipment, and the condition monitoring of the electrical secondary equipment is beneficial to the development of the comprehensive automation of the transformer substation.
