Description
Technical field
The present invention relates to the technical fields of electric power system dispatching operation, more particularly, to power grid under a kind of baseline risk
Accident fast power restoration method.
Background technology
When power grid occurrence of large-area power outage, dispatcher is generally dynamic according to trouble-signal, decompression website and circuit, protection
Make situation, failure judgement position compares the roadmap of accident prediction, determines processing method and telegram in reply path, or by tune
Degree person handles the empirically determined telegram in reply path of power grid accident, this process often consumes the long time, is unfavorable for quickly locating
Director's event；In addition, electric network accident management method differs, it is understood that there may be a variety of telegram in reply paths need to discuss when dispatcher is handled true
Fixed a certain telegram in reply path.
Invention content
The present invention is at least one defect overcome described in the above-mentioned prior art, provides power grid accident under a kind of baseline risk
Fast power restoration method, the support platform of application schedules automated system establish telegram in reply path optimal under all kinds of power grid accidents
Scheme base, when power grid accident occurs, can quickly simulated accident is sent a telegram in reply path in dispatch automated system, and will be optimal
Telegram in reply path is shown by dynamically leading the form of figure, and substitution is in the past refering to the roadmap of accident prediction or by scheduling
Member experience come determine telegram in reply path method.
The technical scheme is that：A kind of power grid accident fast power restoration method under baseline risk, wherein including decision model
Block, the telegram in reply module being connect with decision-making module, the computing module being connect with telegram in reply module；

Action logic action in unit；
The computing module includes：Topology calculating, Load flow calculation and short circuit calculation；Service is provided during telegram in reply, when opening
Off status by coloring, the modes such as out-of-limit provides intuitive displaying after changing for dispatcher.Since telegram in reply shows the time
Limitation, frequent movement switch brings frequent topological Load flow calculation, has higher requirement to calculating speed.
In the present invention, when accident occurs for power grid, the unpromising dispatcher of EMS system does decision and provides the complementary of service
Software, dispatcher can only be by checking SCADA alarm signals, according to protection act information analysis abort situation, in conjunction with current
The method of operation, system loading determine processing method and restoration path etc..Often consuming the long period in this process influences
Telegram in reply efficiency, and dispatcher is needed to have abundant experiences of power accidents disposal.Thus propose that power grid accident is quick under baseline risk
Telegram in reply leads diagram technology, quickly determines that processing scheme selectes optimal telegram in reply path in accident to auxiliary dispatching personnel, when
When baseline risk power grid accident occurs for riverhead power grid, according to prestoring, model Dynamic Display in a manner of switch changed position, topology coloring is multiple
Electric process.By using EMS system data, generates dynamic telegram in reply at DTS system interface and lead figure, topology, which calculates, realizes Dynamic Display
The optimal telegram in reply path when baseline risk power grid accident occurs.This system can be stored in a manner of section, load data and model,
And refresh newest gathered data, various risk cases are triggered by leading figure interface simulation, inverting accident process is not influencing
In the case of SCADA system normal operation, the process that simulated accident is sent a telegram in reply when handling can simultaneously serve as dispatcher's skills training
With the platform of promotion.
Specifically, the decision-making module includes establishing scheme base, establishes scheme base and include accident event, send a telegram in reply to switch and hold
Act part and corresponding trend section；
Start after executing telegram in reply, first carries out event of failure combination relay protection and automatic device model reappears phenomenon of the failure, later
Execute on off sequence one by one, including Fault Isolation, telegram in reply and the completion of falling load telegram in reply process.
The central monitoring position includes measuring monitor,
It measures monitor and mainly monitors measuring value, short circuit calculation value, equipment live state and switch division state；When detection limit is sent out
The data after variation are sent to control centre after changing；Wherein electriferous state and switch division state, state value only has two
A need to judge it is different；And measuring value, short circuit calculation value need to consider variation reference value, different types of monitoring variable
Detected value is different；Judgment mode is：
WhereinTo change reference value,For last computation value,For the value of this calculating.
The control centre is algorithm core, and all devices have been loaded when creating, and is monitored when receiving
After the signal at center, the device involved by signal is filtered out, whether is started by decision logic determining device and manner of execution；Control
Center processed is also responsible for the traffic control of whole process, including the time counts and call as needed auxiliary calculating, telegram in reply process letter
Breath statistics etc..
Compared with prior art, advantageous effect is：Pass through each Substation parameters of EMS system, circuit model and connection relation
Establish the telegram in reply model under riverhead electric network wiring scheme and the various baseline risk accidents of storage.Stress model triggers accident event,
Inverting accident process selects optimal telegram in reply path events, multiple by tidal current chart Dynamic Display with switch motion, equipment coloring mode
Electric process, and generate Brief News.Whole process does not influence the normal operation of SCADA system.
