摘 要:廣東電網(wǎng)負荷特性具有峰谷差大、負荷高峰以及低谷銜接區(qū)間負荷爬升、下降速度極快的特點,為了更好地量化評估省內機組日發(fā)電計劃和西電曲線配合的合理性,對廣東電網(wǎng)調峰調頻現(xiàn)狀進行了分析,并構建了一套日發(fā)電計劃合理性評估指標體系,該體系包含速率指標、趨勢指標、調峰指標,分別解決省內機組和西電調節(jié)速率不相匹配、省內火電機組反調以及火電機組退AGC調峰的問題,實際應用表明,該指標提升了日發(fā)電計劃安排的安全性以及與實時調度銜接的順暢性。
關鍵詞:日發(fā)電計劃;速率指標;趨勢指標;調峰指標

Abstract: The power load of Guangdong power grid has a large peak-valley difference, and varies sharply between peak and valley join sections during some periods. In order to carry out better quantitative evaluation for the units daily generation scheduling in the province and the rationality of western electric curve coordination, this paper analyzed the current situation of Guangdong power grid peak shaving index and frequency modulation and established a set of daily generation scheduling rationality evaluation target system, including speed indexes, tendency indexes and peak shaving indexes and solving the problems such as the non-matching between the units in the province and western electric adjusting speed, thermal power generating unit anti-regulation in the province and quitting automatic gain control (AGC) peak shaving. The practical application shows that this index promotes the security of daily generation scheduling arrangement and the smoothness of real-time scheduling join.
Key words: daily generation scheduling; rate index; trade index; peak shaving index
