Description
Technical field
The invention belongs to power transmission and distribution technical field, particularly relate to a kind of HVDC (High Voltage Direct Current) converter substation alternating current filter field method for arranging.
Background technology
Alternating current filter field is part important in HVDC (High Voltage Direct Current) converter substation, and it is made up of large group of several alternating current filters, and large group of each alternating current filter comprises several alternating current filter groups and several shunt capacitor groups.Alternating current filter place accounts for about 1/4 ~ 1/3 of whole current conversion station place.The layout optimization in alternating current filter place, directly affects the size of general layout, and is directly connected to the key element of many engineerings such as construction investment, equipment and personal security, operation maintenance etc.
At present, alternating current filter field method for arranging mainly contains " yi word pattern " and " matrix pattern " two kinds.
The feature that " yi word pattern " is arranged is, in large group, each alternating current filter group arranged side by side and shunt capacitor group are arranged in the same side of bus.The advantage that " yi word pattern " is arranged is that operation maintenance is comparatively convenient, and large group exchanges inlet wire can adopt overhead wire, and in every large group, small set is that odd number or even number all can well adapt to.But because the group in large group is different in size, in general alternating current filter group head, and shunt capacitor group is shorter, therefore arrange that longitudinal size is controlled by the alternating current filter group grown most, cause filter field to take up an area comparatively large, in place, vacant lot is more, and Land_use change is insufficient.
The feature that " matrix pattern " is arranged is, great Zu Zhongge group is arranged in the both sides of large group bus rod, forms a sphere of movements for the elephants.Alternating current filter group and shunt capacitor group apportion arrange by " matrix pattern ", arrange that longitudinal size reduces to some extent, thus have compressed overall dimensions.But when in every large group, small set is odd number, " matrix pattern " arranges the restriction owing to organizing greatly bus, sphere of movements for the elephants is by formation one piece of vacant lot, and cause floor space comparatively large, Land_use change is insufficient.Simultaneously, when adopting " matrix pattern " to arrange, large group exchanges inlet wire and GIL pipe mother generally need be adopted to be deep into inside, filter field carry out drawing connecing, and the female length of GIL pipe needs longer, and this also makes to adopt the arrangement generally not adopting " matrix pattern " during overhead wire adopting large group to exchange inlet wire.
Summary of the invention:
The present invention will for above-mentioned background technology Problems existing, a kind of HVDC (High Voltage Direct Current) converter substation alternating current filter field method for arranging is provided, Land_use change is comparatively abundant, and large group of simultaneous adaptation can exchange the mode that inlet wire adopts overhead wire or GIL pipe bus, adjacent group can not belong to the situation of same large group.
For solving the problems of the technologies described above, technical scheme of the present invention is
A kind of HVDC (High Voltage Direct Current) converter substation alternating current filter field method for arranging, HVDC (High Voltage Direct Current) converter substation comprises combined frame work, large group exchanges inlet wire, group exchanges inlet wire, group exchanges inlet wire power distribution equipment, several quadrature network group and bus lightning arrester, in combined frame work, be provided with at least two groups large group of bus rod draw respectively and be connected to large group and exchange inlet wire, often group large group bus rod connects several small component stream buses respectively, and each group shunting bus leading is connected to group's inlet wire of each quadrature network group; When the quadrature network group that connects of shunting bus of adjacent group belong to two differences organize greatly time, adjacent group's shunting bus is electrically upper to be disconnected, and group's shunting bus connects two groups of corresponding large group of bus rods respectively; When adjacent group shunting bus connect quadrature network group belong to same large group time, adjacent group shunting bus electrical communication, one group of large group of bus rod wherein corresponding to group's shunting bus connection.
Preferably, large group bus rod is connected to group's shunting bus by lower line lead.
Preferably, often the both sides of group large group bus rod are fixed on combined frame work by strain insulator string.
