摘要/Abstract

摘要： 基于当前湖南电网的受电能力,根据酒泉—湖南特高压直流投运初期受端湖南电网的最新网架和负荷情况,分析了特高压直流与常规电源机组的差异以及由此引起的湖南电网受电能力变化,梳理了负荷模型、同步调相机、网络建模方式、开机方式、负荷总量、机组旋转备用、重要断面功率等因素对特高压直流投运初期湖南电网受电能力的影响,特别是对酒泉—湖南特高压直流输送能力的影响。其中负荷模型、同步调相机、网络建模方式和开机方式的影响较大,而负荷总量、机组旋转备用和重要断面功率的影响较小。计算结果为酒泉—湖南特高压直流的调试和运行方式安排提供了参考。

Abstract: Based on current power receiving capability of Hunan power grid, difference between UHVDC and conventional unit is analyzed. Change of power receiving capability of Hunan power grid is calculated according to the latest network and load level during initial operation of UHVDC project from Jiuquan to Hunan. Impacts of different factors on power receiving capability of receiving-end power grid are compared, including load model, synchronous condenser, network modeling mode, power start-up mode, total load level, spinning reserve ratio and important sections power. The impacts on transmission capability of UHVDC project from Jiuquan to Hunan are discussed in detail. From the analysis, load model, synchronous condenser, network modeling mode and power start-up mode have larger impact than total load level, spinning reserve ratio and important sections power. The results offer references for testing and operation mode arrangement of UHVDC project from Jiuquan to Hunan.

Key words: UHVDC, receiving-end power grid, power receiving capability, sensitivity analysis
