Description

Construction method for transformer substation integrated anti-misoperation safety control platform
Technical Field
The application belongs to the field of transformer substation management, and particularly relates to a construction method for an integrated anti-misoperation safety control platform of a transformer substation.
Background
At present, the types of misoperation prevention of a transformer substation comprise mechanical misoperation prevention, electrical misoperation prevention, electromagnetic misoperation prevention, microcomputer misoperation prevention and the like, and the external expression form of the misoperation prevention mainly comprises an operating mechanism, a five-prevention lockset, an electromagnetic lockset, a sealed unlocking key, an additional grounding wire management cabinet and the like. In this year, a strategic target of building an internationally leading energy internet enterprise with Chinese characteristics is established by national power grid companies, the operation and maintenance major of power transformation takes flattening, intensive and specialized management as a main line, operation and inspection integrated structure optimization and adjustment are implemented, and lean management implemented after adjustment puts higher requirements on the working efficiency and the safety control level of the power transformation station.
At present, the main problems of the transformer substation for preventing error safety from being intensified and lean management are as follows:
1) the unlocking key still mainly adopts an envelope sealing mode, so that the illegal use of the unlocking key cannot be fundamentally avoided, the phenomenon of private unsealing sometimes occurs, and the security management cannot be forced;
2) the error-prevention supervision of secondary equipment such as a pressure plate and an air switch is lacked, and a malignant power grid event which enlarges the accident range due to the failure or misoperation of a relay protection device caused by the missed throwing and the wrong throwing of the pressure plate occurs occasionally, so that great economic and social losses are caused;
3) the situation that various anti-error measures fight against each other is common, and one switching operation relates to the operation of a plurality of anti-error management systems, so that the operation difficulty is increased, and the working efficiency is reduced;
4) the existing anti-error management system is still mostly an offline system, and the real-time performance of anti-error management information is not strong.
5) After the hidden danger of the special misoperation-preventive locking is investigated, the locking of the high-voltage switch cabinet and the locking of the net door and the grounding wire are still not perfect, and an misoperation-preventive blind spot exists;
6) the state of the secondary equipment still depends on manual inspection, and a real-time acquisition and control means is lacked;
7) the anti-misoperation unlocking and the conventional unlocking operation are mixed in a cross mode in the switching operation, and the burden of operators is heavy and the efficiency is low.
8) The emergency unlocking key lacks management and control in field operation, does not have the function of appointed unlocking equipment, and has potential safety hazard of mistaken entering interval unlocking operation;
9) the temporary grounding wire is taken and used without being technically associated with a microcomputer anti-misoperation system, so that the temporary grounding wire can be taken randomly and even left on site;
10) safety tools and appliances in the transformer substation are various in types, the taking and using of the safety tools and appliances are lack of technical association with operation tasks, and once the conditions of wrong taking and missing taking occur, normal operation of switching operation is influenced.
At present, the problems are paid high attention by operation and maintenance management units of transformer substations, and related manufacturers develop related products. For example, the anti-misoperation unlocking key management cabinet replaces an envelope to realize forced sealing and online management on the unlocking key, when unlocking operation is needed, an application is made to an anti-misoperation accountability manager, the anti-misoperation unlocking key management cabinet authorizes the anti-misoperation unlocking key to be taken after remote authorization of the anti-misoperation accountability manager, and the possibility of taking the anti-misoperation unlocking key privately does not exist; the intelligent pressing plate and air switch monitoring system fills the blank of secondary equipment state monitoring, and realizes the state monitoring of the relay protection and the automatic equipment pressing plate and air switch. However, the above products still have their own battles, and the mutual information is not intercommunicated and shared, so that they are still inconvenient to use, and do not play a significant role in improving the working efficiency and the level of security control.
