Saliency-Sensitive Parametric Average-Value Modeling of Machine-Rectifier Systems--Part II: Model Characterization

“…As expected, the previous PAVM parametric functions are coincident with the proposed SSPAVM parametric functions at the current angles on which they are based. These multidimensional parametric functions can serve as the basis for a SSPAVM [20] that, from the results presented herein, can be expected to perform more accurately in dynamic situations, particularly for more salient machinerectifier systems.…”

“…A novel approach for obtaining the essential nonlinear parametric functions required to develop a SSPAVM of the synchronous machine-rectifier system is discussed herein. This procedure provides the necessary lookup table values required for the application of the SSPAVM (developed in [20]). This procedure is demonstrated and compared with the lookup table values that are obtained when using the previous PAVM.…”

“…This paper is second in the series on SSPAVMs of machine-rectifier systems. Part I [20] presents the modeling and simulation, and Part II describes the multidimensional characterization approach.…”

“…The fundamental contributions of this work are 1) to demonstrate that the rectifier parametric functions can be represented as functions of both the dynamic impedance and the current angle, 2) to propose a method of extracting the two-dimensional lookup table values required to represent these functions, and 3) to show how previous PAVMs are unable to represent the rectifier parametric functions during transient events, particularly for more salient synchronous machines. This approach is used in developing the saliency-sensitive PAVM (SSPAVM) of the machine-rectifier systems proposed in [20].…”
