500kv transformer station of China adopts 550kv/220kv/66kv tertiary voltage, and low-pressure side access reactive power compensator and station electricity consumption are the important component parts of transformer station.
At present in Substation Design, generally stress the design optimization of voltage levels, by optimizing wiring patterns, adopting compact device, compressing the measures such as power distribution equipment size, improve the reliability of transformer station, reduce floor space, reduce project cost.But initial thinking and pattern are still continued to main transformer low-pressure side, all adopt conventional equipment and ordinary distribution device, there is no obvious development and change for many years, take up an area very area large, as adopted in the 500kv transformer station of compact device in high pressure side, the occupation of land of main transformer low-pressure side reaches 26 ~ 31% of the full station gross area.
Along with the high speed development of power grid construction, transformer station's scale and capacity increasing, the problem that main transformer low-pressure side equipment increases, floor space is large is also more and more outstanding.Because soil is non-renewable resources; for the fundamental state policy implementing Appropriate application soil further, conscientiously protect farmland; in the urgent need to carrying out the optimal design of main transformer low-pressure side, the solution of these problems will promote the global design level of transformer station, improves operational reliability.
Fig. 1 is the design of existing 500kv main transformer 66kv side structure, and floor space is very large, and it is mainly reflected in following several aspect.
Wherein total loop, 66kv bus and switch branch loop adopt AIS, i.e. open type electric equipment and open type bus.This mode is many due to electric equipment, by the restriction of electric clearance between A, B, C three-phase electric equipment and bus, arranges and leaves larger distance, and floor space is very large, arranges in disorder.
As shown in Figure 2, existing 500kv main transformer 66kv △ busbar is mainly open type, and the lead-out terminal namely extracted from three single-phase transformers directly completes △ winding in A, B, C triple line.This mode is owing to being subject to the restriction of electric clearance between common bus, so floor space is very large, and expend very much the consumption of bus.
Low pressure shunt reactor is one of reactive power compensator important in 500kv transformer station, and Main Function is the absorption electrical network residue charge power of ladder, ensures the scope that voltage stabilization is allowing.Because it is installed in main transformer low-pressure side, be thus called low anti-, be installed on high-tension side high resistance to be different from.For 500kv transformer station, the low anti-form applied in current engineering has " dry-type hollow formula " and " oil immersion iron core type " two kinds.
