摘要/Abstract

摘要： 哈密—郑州特高压直流输电送端电网存在大量的水电机组，掌握水电与火电一次调频特性及其差异对大功率输电安全稳定性具有重要意义。以哈密—郑州特高压直流输电送端电网为研究对象，仿真分析了在较高水电负荷比例条件下不同控制参数对调频控制的影响，结果表明，提高水、火电机组的稳定性和持续性都能显著提高综合调频能力和混合电网的频率稳定性，但水电机组容量的增加会提高电网频率的动态超调。此外，水、火电机组调频指令与负荷的线性度水平都有待进一步规范。

关键词: 特高压直流输电工程, 水火电机组, 动态仿真, 频率控制, 频率稳定

Abstract: Since being a large number of hydro power units in the Hami-Zhengzhou UHVDC transmission network, it is of great significance for the safety and stability of high-power transmission to master the primary frequency characteristics and differences of hydro power and thermal power. In this paper, the Hami-Zhengzhou UHVDC transmission power grid is taken as a typical research object. The influence of different control parameters on the primary frequency control under the condition of higher hydropower load ratio is simulated and analyzed. The joint adjustment scheme between thermal power unit and hydropower unit is given. The control strategy and feasibility suggestions are put forward.

Key words: UHVDC transmission system, hydro-thermal power units, dynamic simulation, frequency control, frequency stability
