Abstract

The present invention provides a DC field equipment control system and method. The solution includes: a DC station control device acquires the position status of the primary equipment and the operating status of the DC protection device, and sends a control command to the primary equipment. The workstation monitors the position status of the primary equipment and the running status of the DC protection device. The primary device regulates the position status according to the control command. In the event of a line fault, the DC protection device regulates the individual pole circuit breakers on the DC bus. Based on this scheme, the operating status of the DC field equipment can be monitored in real time through the workstation, so as to know the location of the fault in real time, and the operation of the DC field equipment can be quickly adjusted based on the DC station control device and the DC protection device, and the fault can be solved in time or prevented in advance , so as to avoid the damage of DC field equipment and greatly improve the working efficiency and economic benefits of the converter station.

Description

technical field [0001] The invention relates to the technical field of electrical maintenance, in particular to a DC field equipment control system and method. Background technique [0002] With the introduction of the concept of Global Energy Internet, the call for grid-connected renewable energy such as wind energy and solar energy is getting louder and louder. However, these renewable energy power generation is intermittent and uncertain, which makes the traditional AC power grid unable to absorb it normally. Flexible DC transmission technology can flexibly control active and reactive power and supply power to weak AC systems. It has become the best choice for grid-connected and long-distance transmission of new energy power generation. Flexible DC transmission adopts a true bipolar structure, and there are many DC devices in the flexible high-voltage converter station, and the cost of construction is higher than that of traditional DC transmission. In addition, the fai...
