Description
Technical field
The invention belongs to supervisory control of substation technical field, more particularly to a kind of transformer station's uneven reason intelligent diagnostics are put down
Platform.
Background technology
With company's intelligent electric energy meter popularization, coulomb collection system construction and scheduling, marketing, fortune inspection operation system not
Disconnected perfect, company information management has covered the defeated change of power network and has sold overall process, and specialty fusion and horizontal improve of data sharing turn into
Following coulomb collection system upgrading and strengthened research research direction.Balance perceives studies and judges research to power network mould with actively intelligence
Type data, electric quantity data carry out Deep integrating research, and correlative study achievement is optimization acquisition scheme, lifts channel design standard,
Strengthen O＆M, it is ensured that real electric quantity data of adopting is complete, monitors the key node information such as critical point, metering, equipment, electricity in real time, grasps
The systemic-function construction such as each level, each link, the balance of each original paper indicate target and direction.At present on transformer station's electricity
The document of energy balance studies is less, Centralizing inspection method, transformer station's electric energy balance type on transformer station's electric energy balance
And the result of study that corresponding calculation etc. is defined and can refer to without unified standard.With the depth of Electric Energy Acquisition System
Enter application, development electric energy balance, which calculates and establishes the monitoring system based on electric energy balance, in real time is possibly realized.And based on electricity
Energy collecting system carries out extensive, comprehensive transformer station's electric energy balance study on monitoring and systemic-function construction, for propping up comprehensively
State's net same period line loss construction etc. is supportted there is not yet correlative study is reported.
EQUILIBRIUM CALCULATION FOR PROCESS needs electric network model used by ensureing to have uniformity with used electric quantity data, causes when electricity
, it is necessary to which EQUILIBRIUM CALCULATION FOR PROCESS program is actively managed EQUILIBRIUM CALCULATION FOR PROCESS model self-organizing adjustment, by switching when there is different condition in pessimistic concurrency control
Moment carries out timeslice cutting, is balanced calculating respectively.Because each transformer station's power network primary structure is not quite identical, metering
Coverage condition also difference, acquisition abnormity and the quality of data are uneven, cause that EQUILIBRIUM CALCULATION FOR PROCESS rule is numerous, and calculating process is non-
Often complexity studies and judges technology to transformer station's balance Comprehensive Evaluation, it is necessary to research and develop efficient intelligence.Power network actual operating state, electricity
Numerous links such as the accuracy of pessimistic concurrency control data, the accuracy of electric quantity acquisition archives, electric quantity acquisition situation, system signal intelligence are all
The appearance of uneven situation may be caused, manually the mode efficiency of lookup uneven reason is low, difficulty is big, it is also desirable to which research and development are accurate
Reliable intelligent diagnostics means, actively discover the accurate location of uneven reason, and alarm prompt.
The content of the invention
The present invention, to EQUILIBRIUM CALCULATION FOR PROCESS model active self-organizing management, realizes transformer station's electricity according to balance monitoring index system
The intelligence of amount balance is studied and judged and uneven reason intelligent diagnostics.
