基于负载优先级的电力分配方法

Electrical Power Distribution Method Based on Load Priority

飞机电力系统供电不足时,需要进行合理的电力分配来保证机上关键负载的用电。通过数学模型描述了飞机电力分配问题,将电力分配问题转化为一个优化问题,提出了一种基于优先级优化的电力分配方法。该方法将优先级引入到负载方程中,形成了新的优化目标函数和约束方程,通过解算优化问题,实现电力的最优化分配。实验结果表明,在飞机电力系统供电不足的情况下,该方法可以确保较高优先级负载的供电优先权,保持左右供电通道的供电平衡,有效抑制负载切换对电气系统供电质量的影响。

When the electrical power on aircraft is insufficient,the power supply priority of vital loads should be guaranteed by distributing the electricity reasonably.Electric distribution problem is described by the mathematical model of the aircraft electric power system,which is transformed into an optimization problem.A new method of the electric distribution is proposed by using the priority model of the loads.The optimization objective function and constraint equation are renewed when the priority is induced in the load models.The resolution of the optimization problem is resolved by calculating the load equations.The experiment results show that the higher priority load can be energized,the power supply balance between the left and the right channel can be kept,and the quality of power supply can be guaranteed effectively.
