摘要

新一代发电机组(EGS)是基于变速发电的概念。柴油机根据机组的负荷变化转速。以最小油耗为最优准则,根据EGS的载荷计算出最优转速。对这种新型EGS概念的动态特性分析表明,负载突然增加时功率和电压下降带来了一些新问题。采用变速技术的EGS概念的动力学特性可以通过使用能量缓冲器来改善。本文讨论了带能量缓冲器的概念EGS的解决方案及其优缺点。

System Variation of Electrical GEN-SET with Energy Buffer
The new generation of electrical generator sets (EGS) is based on the variable speed generation concept. The diesel engine changes the speed according to the load of the set. The optimum speed is hereby calculated according to the load of the EGS with as the optimality criterion the minimum fuel consumption. The analysis of the dynamic behavior of such new EGS concept shows some new problems with power and voltage drops at sudden increase of the load. The dynamical properties of EGS concept with variable speed technology could be improved by using an energy buffer. Solutions of concept EGS with the energy buffer and their advantage or disadvantage are discussed in this paper.
