After the target substation for determining to generate station communication power supply decompression, target substation institute can be obtained respectively The voltage data and current data of other substations in grade route and adjacent level route in addition to target substation at end.
Default time delay majority is set as slightly longer than with regard to the time delay of stratum relaying configuration and station domain layer relaying configuration, such as It can be set to 0.7S.It is greater than the time delay of station domain layer relaying configuration movement by the time delay that setting wide area layer relaying configuration acts, It can be after by carrying out protection act with regard to stratum relaying configuration or station domain layer relaying configuration, if by the event of respective lines Barrier excision, then do not need to carry out protection act again using wide area layer relaying configuration, further reduced involved by failure removal process And scope of power outage, improve the reliability of protection.
S207: judgement respectively removes whether voltage data and current data of the substation target substation Wai Ge at end meet Otherwise the nearly back-up protection criterion of wide area is not processed if satisfied, thening follow the steps S208.
Other substations where getting target substation in grade route and adjacent level route in addition to target substation After the voltage data and current data at place end, the voltage except the substation target substation Wai Ge at end can be judged respectively Whether data and electric current meet the nearly back-up protection criterion of wide area, and the nearly back-up protection criterion of wide area equally can be using conventional phase spacing From protection, ground distance protection criterion, the setting principle of the nearly back-up protection criterion of wide area is also according to every line end metal Property the failure setting principle that can there is sensitivity to be adjusted adjusted, and calculate corresponding adjusting impedance by the setting principle Value, and be calculated impedance value by adjusting impedance setting.If satisfied, thening follow the steps S208, otherwise it is not processed.
S208: from timing at the time of meeting wide area nearly back-up protection criterion, the nearly back-up protection of wide area is utilized with default time delay The substation for meeting the nearly back-up protection criterion of wide area is protected.
Wherein, the nearly back-up protection criterion of the corresponding wide area of the nearly back-up protection of wide area is according to every line end metallicity event Hinder the setting principle setting that there can be sensitivity to be adjusted.
The time delay that the movement of wide area layer relaying configuration can be preset is determining the voltage data and current data got It is middle when there are the data for meeting the nearly back-up protection criterion of wide area, can from timing at the time of meeting wide area nearly back-up protection criterion, The substation for meeting the nearly back-up protection criterion of wide area is protected using the nearly back-up protection of wide area with default time delay.
In a kind of application of specific example, referring to Fig. 3, Fig. 3 is a kind of electric system schematic diagram in the embodiment of the present invention, false If station DC voltage losing occurs for substation B, failure F1 is located in I section of protection scope of substation's B distance, I section of substation's C distance guarantor It protects outside range;Failure F2 is located at outside I section of protection scope of substation's B distance, in I section of protection scope of substation's C distance;And it sets wide The nearly back-up protection in domain can have sensitivity to be adjusted according to line end metallicity failure, when presetting I section of distance protection as 0 Prolong movement, standing with the nearly back-up protection of communication power supply decompression is 0.3S time delay, and the nearly back-up protection of wide area is 0.7S time delay.Separately below To breaking down at F1, F2, using the stratification guard method for the reply station communication power supply decompression that the embodiment of the present invention proposes Afterwards, failure removal process is illustrated.
1, failure at F1
(1) since F1 is located in I section of protection scope of substation's B distance, I section of protection act of distance of substation B is no-delay Trip command is sent to breaker D3 immediately;
(2) since F1 is located at outside I section of protection scope of substation's C distance, I section of protection of distance of substation C is failure to actuate;
(3) lost since substation C detects to communicate with substation B, the nearly back-up protection of investment wide area, at the same at F1 therefore The distance protection criterion of the nearly back-up protection of wide area still has sensitivity when barrier, the nearly back-up protection of wide area will through 0.7s deferred action, to Breaker D4 sends trip command;
(4) failure removal is completed.

2, failure at F2
(1) since F2 is located at outside I section of protection scope of substation's B distance, I section of protection of distance of substation B is failure to actuate;
(2) due to substation B communication power supply decompression, externally all communications lose our station, therefore put into station and lost with communication power supply Press nearly back-up protection, at the same because the distance protection criterion of the nearly back-up protection of failure Shi Zhanyong communication power supply decompression at F2 still have it is sensitive Degree, trip command will be sent to breaker D3 through 0.3s deferred action with the nearly back-up protection of communication power supply decompression by standing;
(3) since F2 is located in I section of protection scope of substation's C distance, I section of protection act of distance of substation C is no-delay Trip command is sent to breaker D4 immediately;
(4) failure removal is completed.
It may be noted that being lost due to detecting to communicate with substation B, two substations also can for substation A and substation D Put into the nearly back-up protection of wide area.Because the nearly back-up protection of wide area is that can have sensitivity progress whole according to line end metallicity failure It is fixed, so its real protection scope can extend to next stage circuit.Therefore, at F2 when failure, substation A and change may be met The nearly back-up protection criterion of the wide area of power station D, leads to breaker D5, D1 tripping after 0.7s is delayed, protection act is caused to surmount.But During waiting 0.7s delay, the station of substation B has been acted with the nearly back-up protection of communication power supply decompression, is delayed through 0.3s The nearly back-up protection criterion of the wide area of tripping circuit breaker D3, substation A and substation D no longer meets.Therefore, by time cooperation, The stratification guard method for the reply station communication power supply decompression that the embodiment of the present invention proposes not will cause protection and surmount.
