This paper shows how generic protection relay models available in planning tools can be augmented with settings that are based on NERC standards or best engineering practice. Selected generic relay models in Siemens PSS®E have been used in dynamic simulations in the proposed approach. Undervoltage, overvoltage, underfrequency, and overfrequency relays have been modeled for each generating unit. Distance-relay...
During recent years, the size of individual wind turbines has grown closer to 10 MW, and the size of wind power plants has increased significantly to 300 MW or more. This growing size of wind power generation requires that careful evaluation of transient stability of the overall grid should be undertaken. This paper attempts to investigate the impact of wind power plant penetration on the transient...
The paper discusses a new idea of the multi-dimensional characteristic ellipsoid (CELL) approach to monitor dynamic behavior of an interconnected power system using phasor measurement unit (PMU) measurement. The multi-dimensional minimum volume enclosing ellipsoid (MVEE) is extracted based on phasor measurements to represent the feature of dynamic behavior of power systems. The orientation matrix...
