微型燃气轮机的微网管理与控制策略

Micro Grid Management and Control Strategy of Micro Gas Turbine

微型燃气轮机通常会配置冷热电负荷,也会选择微型燃气轮机并列运行模式,能有效实现微网中的能量及负荷供应平衡,但微型燃气轮机冷热电负荷小,波动变化大,负荷运行与配置问题比较难于控制。介绍了一种微型燃气轮机串级控制策略,能较好地在满足冷热电等负荷需求的情况下,实现燃气轮机转速及燃料的控制。仿真性能曲线表明,本文介绍的微型燃气轮机的微网管理与控制策略具有响应迅速,控制稳定的特征。

Micro gas turbine usually configuration of cold and heat load,also can choose the micro gas turbine inparallel operation mode,can effectively realize the micro energy and load balance in the supply network,but themicro gas turbine cooling heating load is small,the fluctuating load,operation and configuration problem is moredifficult to control. This paper introduces a cascade control strategy of micro gas turbine,which can realize thespeed control and fuel control of the gas turbine under the condition of meeting the demand of cooling,heatingand electricity. The simulation performance curve shows that the microgrid management and control strategy presented in this paper has the characteristics of fast response and stable control.
