In the new standard, the definition, technical requirements and industry norms of intelligent operation and maintenance of power distribution room are defined for the first time, and the general requirements of safety management, equipment management, facility management, operation and maintenance, personnel requirements and safe power consumption for major events are stipulated, which is of great significance to ensure the safe operation of power distribution room.
At present, there are nearly 1 10000 high-voltage distribution rooms in Beijing, which have various forms of operation and management, and there is no unified standard, which has potential safety hazards. The intelligent operation and maintenance management of distribution room in Beijing is mainly based on GBT3 1989-20 15 "Safety of High Voltage Power Users" and DB11/527-2015, but the above two standards have no specific requirements and relevant technical specifications for intelligent operation and maintenance mode of distribution room.
On September, 2009 19, the group standard "Specification for Intelligent Operation and Maintenance of High-voltage Power User Distribution Room" is an effective supplement to the intelligent operation and maintenance management of distribution room.
The new standard makes it clear that the operation management mode of power distribution room is divided into attended power distribution room and unattended power distribution room. The new standard requires intelligent operation and maintenance enterprises in power distribution rooms to build intelligent operation and maintenance systems based on modern information technologies such as Internet of Things, big data, cloud computing, mobile applications, etc., to build intelligent operation and maintenance centers based on real-time monitoring data, and to carry out intelligent operation and maintenance work in power distribution rooms within their jurisdiction in combination with intelligent operation and maintenance teams, so as to realize the intelligent operation and maintenance mode of "unattended and few people on duty". The new standard restricts the intelligent operation and maintenance enterprises in the distribution room to engage in intelligent operation and maintenance services in strict accordance with technical standards and norms, ends the disorderly competition in the original intelligent operation and maintenance industry in the distribution room, and dispels users' doubts about the compliance of intelligent operation and maintenance in the distribution room, which plays a positive role in promoting the development of the intelligent operation and maintenance market in the distribution room. After the promulgation and implementation of the new standard, the intelligent operation and maintenance mode of distribution room can effectively solve the problem of insufficient professional operation and maintenance personnel in distribution room in Beijing. According to relevant requirements of GBT/3 1989, DB11/527-2015 and Labor Law, the operation and maintenance of power distribution rooms should be carried out by electricians with special operation certificates, that is, each power distribution room should be equipped with at least 6-8 professional electricians. There are about 1 10000 high-pressure self-management units in Beijing, which are generally faced with difficulties in recruiting workers and high labor costs. After the implementation of the new standard, it is clear that the qualified distribution room can realize the intelligent operation and maintenance mode of "unattended and few people on duty", which is an effective supplement to the shortage of human resources and indirectly improves the operation safety of distribution network in Beijing.
Intelligent operation and maintenance relies on the intelligent operation and maintenance system of power distribution room, based on real-time monitoring data, supported by intelligent functions and supported by visualization, and monitoring the operation state of power distribution room in real time with intelligent data analysis technology. Combined with off-line inspection and emergency repair, the safe operation of the distribution room is guaranteed, the operation and maintenance efficiency is improved, the operation and maintenance cost is reduced, and the operation and maintenance mode of the distribution room with few people on duty is realized. The key components of intelligent operation and maintenance include intelligent operation and maintenance center, intelligent operation and maintenance system, unattended distribution room and intelligent operation and maintenance team.
Intelligent operation and maintenance system is the core of intelligent operation and maintenance, and its architecture consists of four layers.
