Embodiment Construction

[0026] In one embodiment, a centralized control system of a multi-terminal flexible DC converter station is provided, such as image 3 As shown, it includes: a converter station 10 and a master server 20 communicatively connected to each converter station 10 .

[0027] Each converter station 10 is provided with an active remote control host 101, and the active remote control host 101 of each converter station is connected to the active server 20 by communication; the active remote control host 101 sends the monitoring information of the corresponding converter station to the main server 20. With the server 20, the master server 20 receives the control instruction, and sends the control instruction to the master telecontrol host 101 of the corresponding converter station.

[0028] The centralized control system of the multi-terminal flexible DC converter station adopts a dual local area network structure to form an open system with distributed functions. On the basis of a unifi...

Abstract

The invention relates to a centralized control method, device and system for multi-end flexible direct current converter stations. The system comprises converter stations and a master server in communication connection with the converter stations. Each converter station is equipped with a master telecontrol host. The master telecontrol host of each converter station is in communication connection with the master server. The master telecontrol hosts send monitoring information of the corresponding converter stations to the master server. The master server receives control instructions and sends the control instructions to the master telecontrol hosts of the corresponding converter stations. The converter stations are controlled and monitored through the server, the cost of configuring a coordination controller for each converter station is reduced, an operator can monitor and control the converter stations through the server, the operation and maintenance working efficiency is greatly improved, and the operation and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a centralized control method, device and system for a multi-terminal flexible DC converter station. Background technique [0002] Flexible DC transmission is based on voltage source converter and pulse width modulation technology to invert DC voltage into AC voltage with controllable amplitude and phase, and can independently and quickly control the transmitted active power and reactive power, which greatly enhances the The flexibility of power transmission has become the most potential power transmission method for the grid connection of renewable energy generation or the grid connection of small-scale power plants. Renewable energy power generation or small-scale power generation systems are generally distributed based on geographical reasons. In order to adapt to the access of power plants to the flexible DC transmission system, a three-terminal to five-terminal multi-term...
