Description
Technical field
The present invention relates to a kind of network prepared auto restart control systems and method based on power network dispatching system EMS.
Background technology
With the continuous raising expanded and user requires power supply quality of China's power grid scale, to the real-time of operation of power networks
Monitoring and analysis and Control propose the higher requirement of update.In order to ensure that power supply reliability and stability, many substations are built-in
Equipment automatic bus, when main power supply breaks down, can tripping main power supply switch, put into Backup Power Switch, shorten
Power off time reduces economic loss.Therefore, fast recovery of power supply, raising intelligence when research prepared auto restart technology is for electric network fault
The safety of power grid plays critical effect.
However, conventional backup auto-activating device can only realize the alternate power autocast on the spot of single substation, when work electricity
When source and stand-by power supply are in different substation, in-put of spare power supply can not be restored power grid power supply by conventional prepared auto restart.For with
Upper problem, some areas establish the prepared auto restart control system based on EMS, and many of which area has selected will be in spare power automatic switching system
In EMS system, this set requires height to Security Checking mechanism, and there are greater risks when operation operates.Secondly it is transmitting electricity

Often have little time to handle and judge, this brings difficulty to discovery failure in time, failure judgement, analysis Failure And Recovery power supply.
With the performance boost of dispatch automated system and perfect, the centralization based on EMS of power grid Networks of Fiber Communications
The realization condition of prepared auto restart scheme is gradually ripe, but also has many problems to need to solve at present.
1) remote signalling of EMS, telemetry and protection signal rely on control centre's system acquisition, with manual or automatic side
Formula definition region prepared auto restart model, adoption status estimation carry out data prediction to telemetering, remote signalling data, and using treated
Data carry out charge condition, discharging condition judges and generate action logic, then after the correction of the electrical network analysis module of EMS, by
SCADA issues operational order, and the switching relevant device in a manner of straighforward operation, realize stand-by power supply automatically engages function.
SCADA system complete whole network data collect need time at least 10s or more, issued using analysis, decision, control command and
It executes, the required time is longer.Such prepared auto restart response speed cannot meet actual motion requirement.
2) action connection point of protective device be connected to measure and control device again on send main station system standby for the region after complex fault
It hauls oneself willingly into, generally requires voltage, the current information of the multiple nodes for knowing synchronization, to realize overload cutoff or load
Respectively, it is also necessary to know section tidal current, the load uncertainty of synchronization.
3) with EMS system identical platform, height is required to Security Checking mechanism, there are greater risks when operation operates.It relies on
In dispatching communication network, susceptible in network failure or when data volume is big.
