The supplying channels wanting load carries out combing and forms guarantor's electric channel and equipment collection；
Protect electric channel by combing and equipment integrates and strong technology can be provided to prop up as the power supply support mission of important load
Hold, help dispatching of power netwoks personnel to grasp electric network composition more fully, rapidly, for power grid security, stably operation offer technology
Ensure.
It step 2, is shown based on the supply path to important load for the tidal current chart；
Be shown the supply path of important load by means of tidal current chart, it is special to carry out the supply line of important load
Render coloring so that it is other supply lines being different from tidal current chart；To at the plant stand of important load place draw border circular areas with
Special sign, other plant stands being different from tidal current chart；Draw arrow to identify trend side on the supply path of important load
To；
Tidal current chart can be shown to combine with visualization by word and be powered path displaying, be dispatcher and side
Formula personnel provide information comprehensive, effective；Supporting that supply path flow process is shown, important load supply path flow chart is from high voltage
Grade is shown to low-voltage-grade, and exhibition information is well arranged, and structure understands.Supply circuit based on the important load of tidal current chart
Point-to-point supply path information between plant stand is shown in footpath, is shown the supply path of important load by means of tidal current chart, adopts
Use multi-layer image rendering technique, do not affect original graphical file information, on tidal current chart, to important load place plant stand and for circuit
Footpath is supported dynamically to render, cancel function, can freely arrange displaying color, and draw on important load supply path arrow with
Mark direction of tide.
It is shown based on the supply path to important load for the topological diagram in addition, may be otherwise, support with mutual (such as point
Hit) mode review voltage levels, obtain nodal information.
Step 3, important load is monitored and security verification in real time；
The real-time supervision to important load, after tripping fault occurs, the affected important load of Realtime Alerts, by tripping operation
Item is analyzed, and obtains trip switch, utilizes tidal current chart simulation to calculate affected important load after switch trip, draws to because of fault
The timely pop-up alarm prompt of important load power failure rising；
When tripping fault occurs, the responsible consumer that pop-up alarm prompt impacts, help dispatcher in time, rapidly
Grasp electric network information.
Security verification operation is carried out to important load, before switch straighforward operation, increases security verify in advance, by tide
Flow field simulation calculates affected important load after drawing road, the important load having a power failure after analyzing operation, evaluates the safety of this operation
Property, the important load preventing maloperation from causing has a power failure.
Whether the present invention mainly builds evaluation system from the angle of responsible consumer security, bring after being operated by analysis
Risk evaluates the security of operation.
Step one reviews end condition by setting and selects Path Terminator Node, the corresponding node of important load and termination
Path between node is supply path.Width first traversal is applied to during the supply path of power system device reviews,
Reviewing end condition such as 220kV bus by setting, power plant's bus selects Path Terminator Node.
The present invention reviews combing supplying channels by the supply path of important load, is formed and protects electric channel and equipment collection, and
In conjunction with visual exhibition method, increase monitoring in real time and anti-error verification to responsible consumer, carry for power grid security, stable operation
Supply technical guarantee.
