Abstract

The invention provides a DC field device control system and method. That scheme comprises: a DC station control device obtains a position state of a primary device and an operation state of a DC protection device, and sends a control command to the primary device. A workstation monitors the position state of the primary device and the operation state of the DC protection device. The primary deviceadjusts the position state according to the control command. In the case of line failure, the DC protection device regulates each pole circuit breaker on the DC bus. Based on this scheme, the workstation can monitor the operation state of the DC field device in real time, so as to obtain the failure position. The operation of the DC field device can be quickly regulated based on the DC station control device and the DC protection device, and the failure can be solved in time or eliminated in advance, the damage of the DC field device is avoided and the working efficiency and the economic benefit of the converter station are greatly improved.

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 the Global Energy Internet, there are growing calls for wind and solar power generation to be connected to the grid. However, these renewable energy power generations are intermittent and uncertain, resulting in the failure of the traditional AC grid to be consumed normally. Flexible DC transmission technology can flexibly control active and reactive power and can supply power to weak AC systems. It has become the best choice for solving new energy generation grid-connected and long-distance transmission. The flexible DC transmission adopts a true bipolar structure. There are many DC equipment in the flexible high-voltage converter station and the cost is higher than that of traditional DC transmission. In addition, the failure of DC field equipment ma...
