In this paper

the multiple influence in the aspects of busbar voltage regulation

system network loss

power transmission channel loss and power transmission capacity of the related substation with the SVC/DC de-icer and SVC device in Dushan substation under different operation duty of the SVC mode

the coordination control of the DC de-icer and SVC device and reactive power installations inside the substation are calculated and analyzed.The coordination control strategy is given to achieve coordination control and economic operation of reactive resources in the substation.The research result in this paper is helpful to reduce the loss of the device itself and its network

and will produce significant economic efficiency

not only provide reference to the design and production of similar equipment in the future

but also provide technical support in improving operation management level

saving energy and reducing loss of such equipment.
