Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
Basic scheme of the present invention is: ultra-high voltage converter station valve group last circuit breaker self adaptation method of discrimination, and step is as follows:
1) if circuit and valve group are with a string, then path is divided into two kinds: the first path is the path of circuit breaker in the middle of this goes here and there 3/2 wiring, and the second path is the path through other string;
If circuit and valve group be not with a string, then path is divided into four kinds: the first path, the second path be go here and there merely through circuit and valve group place two and not identical path;
2) if the first path, the second path all can conducting, then valve group is without last circuit breaker; If there is any one can not conducting in the first path, the second path, then travel through the path between circuit and valve group, if this path can conducting, then count value is increased to each circuit breaker on this path;
3) judge that the maximum circuit breaker of count value is last circuit breaker.
Introduced above, the alternating-current field of extra-high voltage direct-current engineering is divided into double-bus structure, forms between double-bus by going here and there 3/2 wiring more.
As Fig. 2 be valve group with circuit at identical string.In this case, as Fig. 4, valve group and circuit are when identical string, and solid arrow represents the path of circuit breaker in the middle of 3/2 wiring, and namely the first path, is designated as PATH1, and the first path only has one; Dotted arrow represents the path through other string, and namely the second path, is designated as PATH2.Obvious PATH2 comprises mulitpath (identical with the quantity that other are gone here and there).Path representation supply line.
As Fig. 3 be valve group from circuit at different string.As Fig. 6, solid arrow represents the first path, is designated as PATH1; Dotted arrow represents the second path, is designated as PATH2; In this case, the first path and the second path all only have one, and the first path, the second path are being to get lines crossed road merely through two of circuit and valve group place.The third, the 4th kind of path be path through other string, is designated as PATH3, PATH4, obviously the third, the 4th kind of path more than one article, to go here and there quantity relevant to other.
Comprehensive above-mentioned two situations, if the first path, the second path all can conducting, then valve group is without last circuit breaker; If there is any one can not conducting in the first path, the second path, then travel through the path between circuit and valve group, if this path can conducting, then count value is increased to each circuit breaker on this path; The maximum circuit breaker of count value is last circuit breaker.
