Description
Technical field
The present invention relates to the supervision field of intelligent grid secondary device, in particular it relates to the secondary of a kind of intelligent grid sets
Standby analog quantity check method and device.
Background technology
Intelligent grid is to solve the energy and environmental problem, it is achieved the long-term sustainable development of economy and society, with can
During the renewable sources of energy replace non-renewable energy resources, power system prerequisite Comprehensive Control means.Involved by intelligent grid
Content quite varied, such as the access of distributed power source (wind power generation, solar electrical energy generation etc.), Power System Intelligent control technology
(intelligent substation, intelligent scheduling etc.), intelligence primary equipment (intelligent transformer, intelligent breaker etc.), intelligence secondary device (is protected
Protect, oscillograph etc.) etc., be the leader of mankind's new technology revolution.
Secondary device on-line monitor is to realize to the secondary device being distributed in each transformer station (as relay is protected
Protect, the device such as oscillograph) carry out remote automation and monitor and management, by the substation system being distributed in transformer substation end and dispatching terminal
Main station system two parts form.Under normal circumstances, dispatching terminal is sent on after the running status of supervision power transformation station equipment in substation
Main website, with the real-time ruuning situation grasping equipment, finds faulty equipment in time and notifies that operation maintenance personnel carries out defect elimination process, permissible
Effectively prevention or minimizing electrical network major accident occurs；After electric network fault, substation system collects the action of relay protection device automatically
Information simultaneously uploads main website, and dispatching terminal main website also can obtain fault through substation to power transformation station equipment by manual transmitting order to lower levels mode
Information data, professional artificially carries out power grid accident and relay protection analysis of operative action etc. according to the information collected.Two
Secondary device in-service monitoring substantially increases the automatic management level to substation equipment for the professional.
It is to improve the grasp to equipment operating condition, mitigating on-the-spot work that relay protection specialty makes an inspection tour the senior application of work
Make the workload of personnel, and promote lean degree and the real-time that specialty makes an inspection tour work, thus promote relay protection further
Performance factor.For follow-up real realize based on secondary device state can on-line monitoring function secondary device repair based on condition of component provide
Basis, and pass through on-line monitoring and the repair based on condition of component of secondary device, weaken definite value and the logicality detection project of maintenance, thus drop
The overhauling project of the routine test of low protection class device, solves the short difficult problem being difficult to meet repair time requirement of power off time.And
Reduce maintenance difficulty, adapt to O&M integration job requirement, reduce operation maintenance personnel and be engaged in the technical difficulty of specialty service work, from
And farthest given play to the value of relay protection fault information processing system, promote the lean of relay protection specialized management
Level.
For effectively stopping the important relay fail that controllable factor causes, prevent stabilization of power grids malicious event and the bigger face of electrical network
Long-pending power outage, by unified management standard, uniform technical standards, unified operation or work standard, according to management overall process, safeguards full side
The protection apparatus management/control that position, state are controlled entirely requires, it is achieved management and control zero leak, responsibility zero omission, equipment zero doubtful point, operation homodyne
Wrong Thoughts, the comprehensive protection specialty of carrying out of grid requirements makes an inspection tour work, it is intended to control protection equipment running status comprehensively,
Specialty is maked an inspection tour work and is mainly included that regular inspection, annual test, the inspection of key foundation information, daily tour, specialty tour, " N-1 " risk are commented
Estimate and early warning, equipment health state evaluation etc..
With fusion and the development of electrical network scale of big secondary specialty, the professional range that secondary teams and groups are engaged in is increasingly
Extensively, workload is also increasing, and the contradiction between teams and groups' workload and bearing capacity is also more and more prominent.In addition, it is professional at present
Make an inspection tour work to complete mainly by artificial regular inspection, it is impossible to find the hidden trouble of equipment of pilot process in time.And the effect that specialty is maked an inspection tour
There is certain relation with the sense of responsibility of operational staff and technical merit, deviation easily occurs.Therefore, the specialty of people power is relied on
Make an inspection tour work and reached a bottleneck, it is impossible to have and further develop, promote specially in the urgent need to new technological means
The lean degree of industry tour work and real-time, mitigate the operating pressure of personnel.
