Description
Technical field
The invention belongs to relay protection device maintenance field, be specifically related to a kind of relay protection devices state overhaul auxiliary decision system.
Background technology
Compared with World Developed Countries, China still has certain gap in the mean free error time of electric power first and second equipment, reason is many-sided, wherein, one of major reason is the external whole-life cycle fee comparatively early carrying out equipment, replaces traditional prophylactic repair with more advanced repair based on condition of component.
Along with the propelling of intelligent substation technology application, transforming plant primary equipment possesses status monitoring function becomes a kind of technology trends, the propelling of whole-life cycle fee pattern, and traditional primary equipment prophylactic repair pattern progressively develops into repair based on condition of component.
And in secondary device; although be that the transformer station secondary system of representative has progressively adopted the microprocessing possessing self-checking function since the eighties in last century with relay protection devices; but because protection system contains analog input, protective device and breaker tripping and closing output element; and Microcomputer Protection only can self-inspection about 80% link; therefore, protection system still takes traditional prophylactic repair pattern for a long time.
Under this technical background; because protection system maintenance requires that the possibility that primary equipment stops using as a servant will improve greatly; relay protection system must study the on-line monitoring technique under intelligent substation technical background in other words; under the prerequisite guaranteeing relay protection security of system; reduce the power failure probability of primary equipment, safeguard the effect of carrying out primary equipment repair based on condition of component, improve the reliability of electrical network; meanwhile, the probability of relay protection hidden failure is reduced.
In recent years, along with the growth of State Grid Corporation of China's electrical network scale and the continuous lifting of equipment equipment, maintenance workload increases severely and undermanned contradiction, is difficult to adapt to the requirement of lean management and the needs of power network development.For this reason, State Grid Corporation of China carries forward vigorously the change of manufacturing management system, implements power transmission and transformation equipment state overhauling.Within 2007, State Grid Corporation of China starts the repair based on condition of component work organizing power transmission and transformation primary equipment, define a series of file such as " the examination detailed rules and regulations of power transmission and transformation equipment state overhauling ", repair based on condition of component administrative provisions, testing regulations, assessment guidelines, risk assessment directive/guide, life-cycle management instruction, the substantial concrete enforcement advancing equipment state overhauling work.Primary equipment overhaul management system is by the conversion of maintenance to repair based on condition of component that progressively realize a plan, and overhaul of the equipments management system will be more scientific, standardization.Shanghai Power Company has carried out repair based on condition of component in 2008 as primary equipment repair based on condition of component test unit of State Grid Corporation of China, and have passed the examination of State Grid Corporation of China in April, 2009.
Since two thousand nine, for improving quality and the efficiency of relay protection service work, State Grid's dispatching control center takes into full account the many factors such as power grid security, environment, benefit, research and the exploration of relay protection devices Maintenance Mode are organized, within continuous 2 years, listed in the major tasks of relay protection specialty, and in Zhejiang, Anhui, Hebei, Fujian, the company of province such as Hunan carry out pilot.The experience of power transmission and transformation primary equipment repair based on condition of component is conscientiously drawn by each test unit, research relay protection devices structure and technical characteristic, establish based on state evaluation, standardized work is guarantee, comparatively complete relay protection devices repair based on condition of component system, for the further pilot of repair based on condition of component have accumulated useful experience with promoting.
Though relay protection devices repair based on condition of component starts pilot in company of multiple net province, but because state's net does not put into effect relevant policies and directive/guide specification, repair based on condition of component work is substantially all in the exploratory development stage.Therefore, carry out the research of relay protection devices repair based on condition of component, design, exploitation relay protection devices repair based on condition of component evaluation model, significant to next step promotion and implementation relay protection devices repair based on condition of component.
