| 摘要: |
| 在分析相间功率控制器IPC(InterphasePowerController)稳态电路模型的基础上建立了含IPC电力系统线性化数学模型,并以此模型为基础分析了IPC向系统提供转矩的途径和性质。分析表明,IPC本身不能向系统提供阻尼转矩,但会向系统提供负的同步转矩,不利于系统的同步稳定运行。采取合理的控制策略调节IPC参数,可以增加系统的同步转矩和阻尼转矩,保证系统的同步运行,使系统的振荡得到平息,提高系统稳定性。 |

| Abstract: |
| The circuit of IPC(Interphase Power Controller)is discussed and a linear model of the power system with an IPC in one transmission line is given.Based on the model,the form and properties of torque provided by IPC are analyzed.Analysis shows that IPC provides no positive damping torque but negative synchronus torque,which is disadvantageous to power systm stability.By adjusting IPC parameters with appropriate control strategy,positive synchronous torque and damping torque can be provided to keep power system syn-chronization and damp power system oscillation. |
