Electric power loss of SVC devices

at present

is statistically calculated mainly by the power meter

but such loss for each part of SVC device still cannot be measured

neither the actual loss and its proportion of each part of the device at different operation modes of the system and different control modes of SVC is known.Based on above background

a SVC loss calculation software based on the Windows visualization language is compiled in this paper

which can not only perform theoretical calculation on the loss of each part of SVC device

but also preliminarily analyze the calculation result.Finally

the loss of SVC device for Dushan Substation is calculated by such software

the theoretical loss of thyristor valve in SVC

TCR reactors

converter transformers and filters at multiple combination operation modes are obtained

the loss percentage of each part in the total loss is given in accordance with the calculation result

which provides data support for the economic operation of the device in the future.
