Research on Suppression Strategies for Transient Overvoltage of Export Power Network of Large-Scale New Energy Grid-Connected DC Project
摘要: 特高压直流目前是华北、东北、西北等“三北”地区新能源输送至中东部负荷中心的重要方式。由于送端电网相对薄弱,特高压直流在暂态过程中无功大范围波动导致送端电网电压剧烈变化,严重威胁新能源发电和送端电网的安全稳定运行。为此,本文研究不同类型动态无功补偿装置对直流暂态电压波动的影响,提出大规模新能源并网直流送出系统调相机优化配置方案,研究多目标调相机最优配置模型及其求解技术,针对青豫直流提出能满足其近期及远期输送能力的无功配置方案,保证青海送端交直流混合输电系统的安全稳定运行,同时为新能源通过特高压直流外送的送端电网规划设计起到重要指导作用。
Abstract: UHV DC is currently an important way to transport new energy from the “Three Norths” regions of North China, Northeastern China, and the Northwestern District to the load centers in the central and eastern regions. Due to the relatively weak power grid at the sending end, large-scale reactive power fluctuations of UHV DC in the transient process lead to drastic changes in the voltage of the sending end grid, which seriously threatens the safe and stable operation of new energy power generation and the sending end grid. To this end, this paper studies the impact of different types of dynamic reactive power compensation devices on DC transient voltage fluctuations, proposes large-scale new energy grid-connected DC transmission system, and studies the optimal configura-tion model of the multi-objective controller and its solution technology. For Qingyu DC, propose a reactive power configuration plan that can meet its short-term and long-term transmission capaci-ty, ensure the safe and stable operation of Qinghai’s sending-end AC/DC hybrid transmission sys-tem, and plan for the sending-end power grid of new energy through UHV DC transmission Design plays an important guiding role.
