Abstract

Due to the increasing share of inverter-based renewable energy sources and the increased retrofitting of conventional hydropower plants with power electronics, novel possibilities arise for providing damping power in case of occurring inter-area oscillations in power systems. This paper presents a complete model of a variable-speed hydropower plant (VSHP) in a single-machine infinite bus system. The demonstrated analytical model is applied for small-signal stability analysis that contains all relevant converter dynamics and is verified by an additional non-linear time-domain simulation. The damping controller approach located in the full-size converter (FSC) consists of the classical power system stabilizer with additional phase compensation, to which an appropriate wide-area input signal is fed via a phasor measurement unit device. Subsequently, the FSC-VSHP with additional damping algorithm is examined with respect to the significantly higher damping performance with regard to inter-area modes in a three-machine model.

部署全尺寸换流器利用水电站，加强区域间振荡阻尼

由于基于逆变器的可再生能源所占比例越来越大，而且传统水力发电厂越来越多地采用电力电子设备进行改造，因此在电力系统发生区域间振荡时提供阻尼功率的新可能性应运而生。本文介绍了单机无限母线系统中变速水电站 (VSHP) 的完整模型。所展示的分析模型适用于小信号稳定性分析，其中包含所有相关的变流器动态，并通过额外的非线性时域仿真进行了验证。全尺寸变流器（FSC）中的阻尼控制器方法由带有额外相位补偿的经典电力系统稳定器组成，通过相量测量单元装置向其输入适当的广域输入信号。随后，对带有附加阻尼算法的 FSC-VSHP 进行了检验，结果表明，在三机模型中，其对区域间模式的阻尼性能显著提高。

期刊介绍： IET Generation, Transmission & Distribution is intended as a forum for the publication and discussion of current practice and future developments in electric power generation, transmission and distribution. Practical papers in which examples of good present practice can be described and disseminated are particularly sought. Papers of high technical merit relying on mathematical arguments and computation will be considered, but authors are asked to relegate, as far as possible, the details of analysis to an appendix. The scope of IET Generation, Transmission & Distribution includes the following: Design of transmission and distribution systems Operation and control of power generation Power system management, planning and economics Power system operation, protection and control Power system measurement and modelling Computer applications and computational intelligence in power flexible AC or DC transmission systems Special Issues.
