Abstract

The spatial vector transformation, as used in machine vector control, is applied to power system analysis. The proposed methodology is applied to power electronics converters, transformers and transmission lines, as well as to power sources and loads with different connections (delta-wye). This method can be applied to steady-state, transient, unbalanced sources and harmonic analysis. Models obtained using this method are as simple as the per-phase schematic approach. The instantaneous active and reactive power concepts can be expanded and generalized, and new power system control strategies can be developed when power electronics converters are used. Steady-state, transient behavior and harmonic analysis examples and applications using spatial vector theory are presented in order to illustrate the methodology's performance and its advantages. An extension of this method can be applied to faulted systems (unbalanced) using instantaneous symmetric components in poly-phase balanced circuits.

空间矢量在电力系统中的应用

将机器矢量控制中的空间矢量变换应用于电力系统分析。所提出的方法适用于电力电子变换器、变压器和输电线路，以及具有不同连接(三角)的电源和负载。该方法可用于稳态、暂态、不平衡源及谐波分析。用这种方法得到的模型和按相位原理图法一样简单。利用电力电子变流器，可以扩展和推广瞬时有功和无功的概念，开发新的电力系统控制策略。为了说明该方法的性能和优点，给出了使用空间矢量理论进行稳态、暂态和谐波分析的实例和应用。该方法的扩展可以应用于故障系统(不平衡)，在多相平衡电路中使用瞬时对称元件。
