Problems solved by technology

The operating personnel are divided into different teams and are on duty 24 hours a day. The operating personnel receive the relevant dispatching instructions from the dispatching center and perform manual operations or issue instructions in the main control room of the converter station or on the site of the converter station, which requires a lot of manpower. , the operator of a converter station needs more than 20 people, and the labor cost is relatively large
With the development of DC distribution network, the number of DC distribution network converter stations will increase significantly in the future, far exceeding the number of high-voltage converter stations. huge investment

Abstract

The invention discloses a multi-terminal DC distribution network converter station unmanned control method comprising the steps: receiving a scheduling instruction; generating a plurality of control instructions by analyzing the scheduling instruction; and correspondingly allocating the control instructions to each converter station to control operation of each converter station. The operation of the power system can be automatically completed and the manpower cost of configuring the operation personnel on the site of the converter station can be saved.

Description

technical field [0001] The invention relates to the technical field of electric power system control, in particular to an unmanned control method and device for a multi-terminal direct current distribution network converter station. Background technique [0002] The power system has been dominated by alternating current for a long time. From power generation, power transmission, power transformation, power distribution and power consumption, all links are dominated by alternating current. However, with the development and maturity of high-voltage direct current transmission technology, direct current transmission The technology has been widely used in the field of long-distance and large-capacity power transmission. [0003] In terms of the control and operation of the converter station, the existing DC converter stations all adopt the manned operation mode. The operating personnel are divided into different teams and are on duty 24 hours a day. The operating personnel rece...
