Abstract

An electromagnetic design procedure is proposed that allows taking into account the features of jointly utilizing a semiconductor converter and an electric machine in an electric drive system. The parameters of an electric machine are viewed as distributed and found by solving differential equations with distributed parameters, while the variables of control signals are defined by the conventional numerical techniques of a system of ordinary differential equations. The procedure allows defining the potential reserves of magnetoelectrically excited synchronous machines for drilling rig facilities for the power-to-mass ratio. As was shown by the calculations, the choice of the machine’s rated parameters and main dimensions allows using synchronous machines twice as efficiently in terms of power. It is shown that the no-contact and simple design of synchronous reluctance machines means that the opportunities for using them on drilling rigs are great. With properly selected main dimensions and phase current control laws, the specific weight–size parameters of these machines can be improved as compared with their induction counterparts.

石油和天然气设施用电机的电磁设计

摘要

提出了一种电磁设计程序，其允许考虑在电驱动系统中共同使用半导体转换器和电机的特征。通过求解具有分布参数的微分方程，可以将电机的参数视为分布式参数，并找到它们，而控制信号的变量则由常规微分方程系统的常规数值技术定义。该程序允许以功率质量比来定义钻机设施的磁电励磁同步电机的潜在储备。如计算所示，通过选择机器的额定参数和主要尺寸，可以使同步机器在功率方面的使用效率提高两倍。结果表明，同步磁阻电机的非接触式和简单设计意味着在钻机上使用它们的机会很大。用适当选择的主要尺寸和相电流控制法中，这些机器的特定的重的尺寸参数可以与他们的感应同行相比，能够提高。
