Studies of dynamic stability of nodes of electric power systems with asynchronous loading taking into account higher harmonics

摘要

The article considers non-sinusoidal voltage at the nodes of electrical power systems with asynchronous loading. Influence of the non-sinusoidal voltage on the moment developed by the asynchronous engine is described. Influence of value of sliding of the asynchronous engine on possibility of its self-start is investigated. The developed mathematical model for calculating the self-start of the engine taking into account the non-sinusoidal voltage is described. The influence of the weight and size parameters of the asynchronous engine on the behavior of its speed at self-start is investigated. It is shown that non-sinusoidal of voltage leads to longer self-start time of the asynchronous engine.
