A stable operation control method for substation secondary automation equipment

Abstract

The invention relates to a substation secondary automation equipment stable operation control method. A substation secondary automation equipment stable operation control system architecture building method and an information transfer flow are included, and equipment stable operation is monitored through the change of a secondary automation equipment operation index. According to the method, maintenance personnel can be periodically reminded to maintain secondary automation equipment, an equipment fault characteristic is judged when the equipment is failed, a fault impact scope is defined in case of a batch of failures and a fault processing assistant decision is given, and the operation of the substation secondary automation equipment in an ill state or with extended service is prevented.

Description

technical field [0001] The invention belongs to the field of electrotechnical technology, and more precisely, the invention relates to a comprehensive analysis method for early warning of failures of substation secondary automation equipment and demarcating the scope of failures. Background technique [0002] (1) Current status of substation development [0003] In recent years, with the rapid development of the national power system, the number of intelligent substations, control integration, UHV projects, and unattended stations has increased on a large scale. Smart substation has entered the stage of comprehensive construction. In accordance with the overall deployment of smart grid construction, the State Grid Corporation of China has begun to comprehensively build smart substation projects, covering 66kV-750kV voltage levels. Smart substations are composed of advanced, reliable, energy-saving, environmentally friendly, and integrated equipment. Based on high-speed net...

[0005] (2) Current status of substation operation and maintenance

However, some staff tend to ignore the importance of inspection and inspection work; at the same time, some inspection departments are unreasonable in terms of work allocation and personnel arrangement, and there are often phenomena that power equipment is not inspected

[0008] At the same time, with the increase in the number of substations, the increase in operation and maintenance personnel is far behind the development of power grid equipment, and the pressure on operation and maintenance is increasing.
