Description
Technical field
The present invention relates to electric and electronic technical field, more particularly to a kind of SVG to coordinate compensation system and method.
Background technology
SVG (Static Var Generator), i.e. static var compensator, are to refer exclusively to the electric semiconductor by from commutation
Bridge-type current transformer carries out the equipment of reactive-load compensation.It is live in large industrial enterprise and petroleum gas equal energy source company, one
Well matched to have 110KV transformer stations or 35KV transformer stations, these yards have high power load mostly, and are usually provided with two-way height
Press input circuit, it is one standby as a master, when power supply trouble occurs for input circuit all the way wherein, ensure use electric loading thereon according to
So can normal operation.A SVG is equipped with each route road, be each responsible for where circuit reactive-load compensation, when certain all the way
When input circuit breaks down, the load on primary circuit is powered by another way input circuit, but SVG is generally only to residing
Line transformer carries out reactive-load compensation.Now, because input circuit all the way is needed to two-way load supplying, and SVG compensation is only
For line transformer all the way, such compensation effect and not up to predetermined effect, cause the wasting of resources.In addition, for length
Defeated high-voltage line, on high-tension line, that is, reactive loss on the input circuit of electricity consumption enterprise substation transformer is also huge
, particularly in underloading, reactive loss becomes apparent, and also results in the wasting of resources, and cause additional economic to bear to enterprise
Load.
The content of the invention
During for the power supply trouble of generation all the way in the two-way transformer-supplied circuit of transformer station of electricity consumption enterprise, make two
SVG on circuit coordinates to carry out reactive-load compensation, improves reactive-load compensation effect, avoids the wasting of resources, and increases economic efficiency, this hair
