摘要
研究特高压输电对汽轮机组的影响对于实现两者协调发展具有重大意义。阐述了特高压输电技术的基本特点,研究了汽轮机组的运行特性,在此基础上,然后结合某省各大电厂的发电现状,分别从特高压输电正常情况和非正常情况两个方面对汽轮机组的影响展开分析,提出了策略式评估体系以指导一次调频参数的调整,并总结出机组低负荷运行的应对措施。针对特高压输电故障情况下对机组弯扭振动的影响,结合三点故障评估指标提出了整体式在线调整体系以优化机组运行状态,探讨了未来的发展方向和需要解决的问题。
The effect of ultra-high voltage transmission on turbo set was investigated. This study realized harmonious development between ultra-high voltage transmission and turbo set. This paper illustrated the general features of ultra-high voltage transmission and studied the operating characteristic of turbo set. Then, combing the above investigation with current electric power generation of power plants in a province, analysis of the impact of ultra-high voltage transmission on turbo set under normal and abnormal situations was carried out separately. A strategic assessment system to guide primary frequency parameter adjustment was proposed and three measures of low load operation unit were also summarized. In addition, a monolithic line adjustment system was proposed to optimize plant operation after analyzing the bending and torsion vibration of turbo set during the malfunction of ultra-high voltage transmission under three malfunction evaluation index. Moreover, future research directions and questions were prospected.
