摘要

目的:综合异步电动机的数学模型,考虑到电力质量变化对加热和热交换过程的影响,以经济合理地选择保护手段。方法:从理论上证实使用异步电动机的单质量热模型的便利性,用于后者在低质量电力条件下的运行条件,以确定其损失。结果:对异步电动机在额定负载下的运行进行了实验研究。得到的测量结果可以确定单质量热模型的参数、发动机的传热系数和热容系数。感应电机的单质量热模型是用来描述感应电机中发生的热过程的数学模型。这个模型是基于这样一个假设,即所有的马达元件都可以组合成一个在发动机运转过程中加热的整体。该模型假设电机的热容量为常数,电机运行过程中释放的热流与通过电机绕组的电流的平方成正比。此外,该模型假设电机质量与外部环境之间存在导热系数,这影响了散热速率。科学新颖性:考虑到电力质量变化对异步电动机加热和热交换过程的影响,提出了一种利用综合数学模型确定异步电动机损耗的方法。实际意义:所得结果表明所提出的异步电动机在低质量电力网络中运行的热模型是充分性的。考虑到参考文献中许多类型的发动机没有关于传热系数和热容系数的必要数据,并且只给出了某些类型发动机的热时间常数,因此可以根据本文提出的方法获得模型的指定参数值。单质量热模型可用于分析感应电机中发生的热过程和提高电机的效率。特别是,它可以帮助确定电机的最佳运行温度,并计算必要的冷却系统,以确保电机在变负载和变温度条件下稳定运行。

Identification of the thermal process in an induction motor
Purpose: synthesis of a mathematical model of an asynchronous motor, taking into account the impact of changes in the quality of electricity on the processes of heating and heat exchange for an economically justified choice of means of protection. Methodology: Theoretical substantiation of the expediency of using a one-mass thermal model of an asynchronous motor, for the conditions of operation of the latter in conditions of low-quality electricity, in order to determine losses in it. Results: Experimental studies of the operation of an asynchronous motor at nominal load were carried out. The obtained results of the measurements made it possible to determine the parameters of the single-mass thermal model, the heat transfer coefficient of the engine, and the coefficient of its heat capacity.A single-mass thermal model of an induction motor is a mathematical model used to describe the thermal processes occurring in an induction motor. This model is based on the assumption that all motor elements can be combined into one mass that heats up during engine operation. The model assumes that the thermal capacity of the motor is a constant, and the heat flow that is released during the operation of the motor is proportional to the square of the current passing through the motor windings. In addition, the model assumes the presence of thermal conductivity between the mass of the motor and the external environment, which affects the rate of heat dissipation. Scientific novelty: A methodology for determining losses in an asynchronous motor using a synthesized mathematical model is proposed, taking into account the influence of changes in the quality of electricity on the processes of heating and heat exchange in it. Practical significance: The obtained results indicate the adequacy of the proposed thermal model of an asynchronous motor operating in a network with low-quality electricity. Taking into account the fact that for many types of engines in the reference literature,there are no necessary data on the coefficients of heat transfer and heat capacity, and only the thermal time constants for certain types of engines are given, the value of the specified parameters of the model can be obtained on the basis of the methodology presented in the work.A single-mass thermal model can be useful for analyzing the thermal processes occurring in an induction motor and for improving the efficiency of the motor. In particular, it can help determine the optimal operating temperature of the motor, as well as calculate the necessary cooling system to ensure stable operation of the motor under conditions of variable load and temperature conditions.
