The power configuration information of different voltages grade assesses the risk class of the guarantor electricity user in conjunction with power supply risk experts database.Based on confession
Equipment connecting relation on power path generates supply path display diagram by the way of automatic tree layout.
Further, comprising steps of
(1) the main data information for matching Integrated Model and the method for operation is obtained, the connection relationship of equipment room is established；
(2) electric user is protected from target, obtains the device node for protecting electric user, by the connection relationship of device node,
Using topology search technology, the opposite direction along trend flow direction up traces step by step, the equipment passed through during record search, until
Until target voltage grade equipment；
(3) after the completion of searching for, all buses on supply path is counted, the backup power source feelings of every bus are successively analyzed
Condition, and record backup power source number；
(4) power supply risk rule library is combined, judges whether the backup power source number of each voltage class meets condition, and give
Corresponding risk class out；
(5) supply path connection is generated by automatic tree topology technology based on the equipment connecting relation on supply path
Relational graph is simultaneously shown.
Further, the step (2) includes:
(2.1) from electric user equipment node is protected, based on the connection relationship of electric network model equipment, retrospect upwards step by step；
(2.2) equipment in search process is recorded, and forms connection relationship；
(2.3) judge whether to search target voltage grade, if having searched highest voltage level, complete this time and search
Otherwise rope continues the equipment search of next voltage class.
Further, the retrospect target of supply path can be with the equipment for finding a certain voltage class by being manually specified
Path tracing termination condition.
The utility model has the advantages that the present invention is based on main guarantor's power supply areas with one to be classified operation risk analysis method, matched based on master
Integrated Model realizes the whole network supply path search for protecting electric user, and knot contracted areas protects the difference of electric user's power configuration principle
Property and risk deciding grade and level related foundation, building power supply lacks risk rating experts database, and electric user's different voltages grade electricity is protected in analysis
The redundant configuration of source point, assessment protect electricity user's power supply and lack risk, realize main with integral system guarantor's power supply area classification operation
Risk analysis.Meanwhile, it is capable to supply path cluster tool be extracted by Topology service dynamic based on real-time grid state, using tree
Shape layout type automatic Display protects the supply path and its power supply risk of electric user.The method of the present invention can assist in management and running people
Member controls in real time protects electric customer power supply situation, prompt for risk, sound assurance power supply reliability.
Detailed description of the invention
Fig. 1 is the method for the present invention the general frame.
Specific embodiment
Further description of the technical solution of the present invention with reference to the accompanying drawings and examples.
It is of the present invention that operation risk analysis method is classified based on main guarantor's power supply area with one, master is obtained first to be matched
Net Integrated Model and real time operation mode, the supply path of target device is searched by Network topology, and supply path is looked into
It looks for and flows to information according to equipment connecting relation and trend, count all primary equipments on supply path, search different voltages
The standby electricity source point of grade bus obtains the power configuration information of different voltages grade on the supply path, in conjunction with power supply risk
Experts database assesses the risk class of the guarantor electricity user.
Supply path refers to route, the main transformer, switch, disconnecting link from designated user, passed through along the retrospect of trend opposite direction
And the primary equipments such as bus.The retrospect target of supply path can find setting for a certain voltage class by being manually specified
Standby is path tracing termination condition.
Meanwhile based on the equipment connecting relation on supply path, supply path is generated by the way of automatic tree layout
Display diagram.Main guarantor's power supply area classification operation risk analysis method with one supports anticipation mode simultaneously, and implementation is same as above.
Specific step is as follows:
Step 1, the data information for obtaining the main electric network model with one and the method for operation, the connection for establishing equipment room are closed
System, including device name, connecting node, switch state, disconnecting link state, route are active, main transformer winding is active etc.；
Step 2, electric user is protected from target, obtains the device node of the guarantor electricity user, passes through the connection of device node
Relationship simultaneously combines switch, disconnecting link state, and using topology search technology, the opposite direction along trend flow direction is up traced step by step, recorded
The equipment passed through in search procedure, until target voltage grade equipment；
Step 2.1, it is chased after upwards step by step from the electric user equipment node of guarantor based on the connection relationship of electric network model equipment
It traces back, trace back process follows the reversed principle of trend, i.e., carries out next step search when trend is reversed, otherwise exit search；
Step 2.2, the equipment such as main transformer, route, bus, switch, the disconnecting link in search process are recorded, and forms connection and closes
System；
Step 2.3, judge whether to search target voltage grade, if having searched highest voltage level, completing should
Otherwise secondary search continues the equipment search of next voltage class；
Step 3, after the completion of search, all buses on the supply path is counted, the standby electricity of every bus is successively analyzed
Whether source situation can search attachable stand-by heat switch, and record backup power source number；
Step 4, in conjunction with power supply risk rule library, judge whether the backup power source number of each voltage class meets condition,
And provide corresponding risk class；
Step 5, the equipment such as route, main transformer, switch, disconnecting link on supply path are obtained, by automatic tree topology technology,
It generates supply path annexation figure and shows.
It is of the present invention that operation risk analysis method is classified based on main guarantor's power supply area with one, it can be matched based on master
The whole network supply path of electric user is protected in Integrated Model analysis, and power supply is established in the power supply redundancy configuration of analysis different voltages grade
Risk experts database, assessment protect electric user's power supply and lack risk.
