Embodiment Construction

[0021] The technical solution of the present invention is: according to the characteristics of flexible direct current transmission, the server and operator workstation of the operator monitoring system are set in the converter stations at each end, and the server, operator workstation communicate with the pole control and valve control systems to realize control information interaction , The server and operator workstations are interconnected through optical fiber switches to realize the monitoring and control of the entire multi-terminal control system at a single end.

[0022] Below in conjunction with accompanying drawing, the present invention will be further described:

[0023] like figure 2 As shown, taking the four-terminal flexible DC transmission equipment control system as an example, it can also be used in the multi-terminal flexible DC transmission equipment control system.

[0024] The flexible direct current transmission control system is distributed in four c...

Abstract

The invention provides a multi-end flexible direct current transmission operator control system and a control method thereof. The multi-end flexible direct current transmission operator control system comprises operator workstations at all ends and a server, wherein both the operator workstations at all ends and the server are provided with corresponding network interfaces and connected with a communication network for information interaction of convertor station at the ends. The coordination control of the multi-end control system is achieved by adopting the control method, the labor cost is saved, and the control efficiency of the system is improved.

Description

technical field [0001] The invention relates to a multi-terminal flexible direct current transmission operator control system and a control method thereof, belonging to the field of electric power system automatic multi-terminal flexible direct current monitoring. Background technique [0002] Light DC transmission technology is a new type of DC transmission technology developed in the 1990s. The core is to use a voltage source converter (VSC) composed of fully controlled devices (such as GTO and IGBT) for commutation. Flexible DC transmission is an important piece of equipment for building smart grids. Compared with traditional methods, flexible DC transmission has stronger technologies in island power supply, urban distribution network capacity expansion, AC system interconnection, and large-scale wind farm grid integration. The advantage is a strategic choice to change the development pattern of large power grids. It is a milestone. [0003] The operator control system ...
