Description

Based on share the main transformer backup protection Accelerated trip method of information across interval
Technical field
The invention belongs to technical field of power systems, relate in particular to a kind of main transformer backup protection Accelerated trip method based on across the shared information in interval that is applied to intelligent substation.
Background technology
Main transformer protection is comprised of main protection and various backup protection, backup protection comprised high-pressure side and in, the low pressure protection of surveying.Common, the switching value that main transformer protection gathers comprises the high, medium and low three side circuit breaker positions of main transformer, does not gather the mother section breaker positional information that each is surveyed.When each side trip protection logic meets, the order of tripping operation is that the mother section breaker of first jumping each side of main transformer is jumped each side circuit breaker of main transformer again, as shown in Fig. 3 solid line part.According to this Trip Logic, if mother is divided under position or mother charge condition, this drives the tripping operation of mother section breaker without sending out trip signal to mother intelligent terminal again, but because main transformer protection is not known its deciliter situation, therefore can waste the regular hour.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the invention provides a kind of based on share the main transformer backup protection Accelerated trip method of information across interval.Object is that the positional information of mother section breaker is sent in main transformer protection, divides under position or mother charge condition and realizes and accelerate to jump each side circuit breaker of main transformer, thereby shorten the trip time in mother, improves the quick-action of protection, promotes the performance of protection.
In order to realize foregoing invention object, the present invention is achieved through the following technical solutions:
Based on share the main transformer backup protection Accelerated trip method of information across interval, be that medium/low pressure rear flank at main transformer increases an Accelerated trip logic in for defencive function, main transformer mesolow side backup protection utilization realizes and accelerates to differentiate across the shared information at interval;
When adopting under net hop pattern at main transformer protection net, because main transformer high pressure, mesolow side mother positional information are sent to during each top-cross changes planes by its corresponding mother interval intelligent terminal, and main transformer protection has connected main transformer high-pressure side switch and main transformer mesolow top-cross is changed planes, can realize mother positional information and be passed in main transformer protection;
When directly adopting under straight hop pattern at main transformer, on main transformer protection, set up three fibre circuits and be connected respectively on mother interval intelligent terminal corresponding to main transformer high-pressure side, medium voltage side and low-pressure side, the function of directly adopting to realize mother information;
No matter adopt under net hop pattern directly adopting straight jumping or net, the Trip Logic that first main transformer protection utilizes the analogue quantity switch amount information sending to carry out backup protection is differentiated, if now main transformer protection judgement transformer side circuit breaker should trip, differentiate again this side bus and whether be in a minute position/charged state, if so, direct this side circuit breaker of tripping main transformer; If not, according to the tripping operation order under general case, i.e. this side bus of first tripping, then this side main transformer circuit breaker of tripping.
Described mother interval intelligent terminal is sent to its corresponding section breaker information in main transformer protection in GOOSE mode.
Described mother interval intelligent terminal with being connected of main transformer protection is: net is adopted under net hop pattern without increasing any optical fiber; Directly adopting needs to increase an optical fiber under straight hop pattern mother interval intelligent terminal is connected with main transformer protection.
Described main transformer mesolow side backup protection utilization realizes acceleration differentiation across the shared information at interval, in the situation that Trip Logic is satisfied, if now the position of each side mother section breaker of main transformer is under minute position or charge condition, main transformer protection, without first sending out the section breaker of trip command to each side bus, is directly sent out trip signal to each side intelligent terminal again; If now the position of each side mother section breaker of main transformer is co-bit, by common tripping operation mode, trip, first jump each side mother section breaker, then jump each side circuit breaker of main transformer.
Described main transformer mesolow side backup protection utilization realizes acceleration differentiation across the shared information at interval, no matter adopt under net hop pattern directly adopting straight jumping or net, the Trip Logic that first main transformer protection utilizes the analogue quantity switch amount information sending to carry out backup protection is differentiated, if now main transformer protection judgement transformer side circuit breaker should trip, differentiate again this side bus and whether be in a minute position/charged state, if so, direct this side circuit breaker of tripping main transformer; If not, according to the tripping operation order under general case, i.e. this side bus of first tripping, then this side main transformer circuit breaker of tripping.
Advantage of the present invention and beneficial effect are: the present invention is sent to the positional information of mother section breaker in main transformer protection; in mother, divide under position or mother charge condition and realize and accelerate to jump each side circuit breaker of main transformer; thereby shorten the trip time; there is the quick-action that improves protection, promote the remarkable advantages such as performance of protection.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Fig. 1 is that before and after the present invention adopts Accelerated trip method, net is adopted main transformer protection typical case connection layout under net hop pattern;
Fig. 2 directly adopts main transformer protection typical case connection layout under straight hop pattern before and after the present invention adopts Accelerated trip method;
