Description
Technical field
The invention belongs to be directed to reactive power compensation technology field, and in particular to a kind of quick determination side in 10kv reactive-load compensations position
Method.
Background technology
Current period, applying for 10kv high voltage distribution networks gradually increase under the promotion of economic development, various power consumers
The control of reactive power is required also to be gradually increased, power distribution network administrative staff implement idle benefit in the end of user to power grid
It repays, must can reach getting twice the result with half the effort for compensation work, compensation work is made to realize highest comprehensive performance and best economy
Benefit.In the way of this idle dispersion compensation again as grouping compensation, compensated using dispersion, mainly by means of will
Capacitor group is installed in the busbar position etc. of the either low pressure of the terminal power distribution net high pressure with lower power factor, to make
Reactive factor is adjusted, and correction and adjustment for power factor are finally reached.This compensation way key be for
Voltage is adjusted, quality of voltage is made to be improved, avoids the loss of voltage, to improve it for electric energy for system operation
Power.But the application of this mode needs to come based on the maximum reactive requirement that the low-pressure side of distribution transformer has
Capacity is adjusted, and the low-pressure side of different power transformation devices has different load fluctuation situations, this may result in certain large capacities
Capacitor is in idle situation in low load condition.In addition showing simply by setting in the determination of reactive-load compensation position
Computer obtain, computer at the scene is set and is frequently encountered some moist environment, at present often setting
Computer at the scene puts the dehumidifying cabinet for being attached to the computer of setting at the scene into, periodically dehumidifies to ensure that its is good in this way
Working performance, but dehumidify cabinet work when it is necessary to ensure it the problem of gap not occurring, will make in case of gap
The moisture obtained in external environment infilters dehumidifying cabinet, and the result that can thus dehumidify is undesirable, serious so that dehumidifying cabinet can not
Normal operation often combines one side rabbet joint type framework in present dehumidifying cabinet, because cabinet and its cover board and flipping side
Construction is it occur frequently that gap, the capacitor that may result in large capacity in this way are in the situation being idle, outside in low load condition
Moisture in environment infilters dehumidifying cabinet.And the computer being arranged at the scene can not effectively carry the data to a distant place.And
The operation conditions of dehumidifying cabinet can not be observed in real time.
Invention content
It is an object of the invention to provide a kind of 10kv reactive-load compensations position fast determination methods, and 10kv reactive-load compensations are arranged first
