Abstract

To solve the problem that the multi-terminal HVDC system which adopts fixed coefficient droop control has unacceptable DC voltage deviation and terrible power distribution ability, an adaptive DC voltage droop controller is designed which can give consideration to both DC voltage control ability and power distribution ability. Firstly, the basic structure of MTDC and MMC is introduced. Then a novel adaptive DC voltage droop controller is designed based on the local electric variables of the converters running in droop control mode. Finally, $\mathrm{a}\pm 200$ kv four-terminal HVDC system simulation model has been built in PSCAD/EMTDC, the adaptive voltage droop control strategy introduced in this dissertation is validated. The simulation results show that compared with the traditional droop controller, the proposed adaptive DC voltage droop controller has stronger DC voltage control ability when the power flowing through a converter is greater than the reference, or contrariwise, the controller has better power distribution ability.

一种考虑局部电变量的MMC-MTDC自适应直流电压降控制方法

针对采用固定系数下垂控制的多端高压直流系统直流电压偏差难以接受、配电能力差的问题，设计了一种既能兼顾直流电压控制能力又能兼顾配电能力的自适应直流电压下垂控制器。首先介绍了MTDC和MMC的基本结构。在此基础上，根据变换器的局部电变量，设计了一种自适应直流电压下垂控制器。最后，在PSCAD/EMTDC中建立了$\ mathm {a}\pm 200$ kv四端高压直流系统仿真模型，对本文引入的自适应电压降控制策略进行了验证。仿真结果表明，与传统的直流电压下垂控制器相比，所提出的自适应直流电压下垂控制器在流过变换器的功率大于参考时具有更强的直流电压控制能力，反之具有更好的功率分配能力。
