Abstract In its industrial application, three-phase induction motors are subject to the drive of high inertial loads. This fact results in the storage of kinetic energy during their operation. Thereby, this work presents a method to connect the electric grid of a Squirrel Cage Induction Generator rotor (SCIG) coupled to a cylindrical flywheel of high inertial content to reduce small disturbances in the electric grid. The proposal is validated by means of experimental tests on a bench using toroidal inductors to mitigate the effects of the current transients in the injection of kinetic energy converted into electrical energy in the grid. The results showed that this system can supply a short-time undervoltage disturbance of up to 0.2 pu three-phase and 0.4 pu per phase.

应用于同步电网发电机系统的飞轮储能改善电能质量的建议

摘要 在工业应用中，三相异步电动机受到高惯性负载的驱动。这一事实导致在其运行期间储存动能。因此，这项工作提出了一种连接耦合到高惯性含量的圆柱形飞轮的鼠笼式感应发电机转子 (SCIG) 电网的方法，以减少电网中的小扰动。该提议通过在工作台上的实验测试得到验证，使用环形电感器来减轻电流瞬变对电网中转换为电能的动能注入的影响。结果表明，该系统可以提供高达 0.2 pu 三相和每相 0.4 pu 的短时欠压扰动。
