Energy saving scheduling model of the constant frequency motor in active distribution network based on vector control

针对传统配电网恒频电机调度模型抗干扰能力差、调度效果不佳的问题,提出基于矢量控制的主动配电网恒频电机节能调度模型。首先设计了恒频电机单相等效电路,然后依据等效电路设计主动配电网恒频电机控制框架,通过电机电流分量计算和相位变换进行闭环的自行控制,实现位置和速度相互转换的节能控制。结合矢量控制结果,从运行成本最低值控制和滚动修正两个方面入手,构建节能调度目标函数,并给出了主动配电网恒频电机节能调度流程,完成模型设计。为验证模型效果,设计了对比实验,研究结果表明,该调度模型具有很强的抗干扰能力,CPU占用率更低。

In order to solve the problem that the traditional constant frequency motor scheduling model of distribution network has poor anti-interference ability and poor dispatching effect,an energy saving dispatching model of active distribution network constant frequency motor based on vector control is proposed.Firstly,the single-phase equivalent circuit of constant frequency motor is designed,and then the control framework of constant frequency motor of active distribution network is designed according to the equivalent circuit.The closed loop self-control is carried out through the calculation of motor current component and phase transformation,and the energy saving control of position and speed conversion is realized.Based on the results of vector control,the objective function of energy saving scheduling is constructed from two aspects of minimum operating cost control and rolling correction,and the energy saving scheduling of constant frequency motor in active distribution network is given.In order to verify the effect of the model,a comparative experiment is designed.The results show that the scheduling model has strong anti-interference ability and the CPU occupancy rate is lower.
