In this paper, the modeling of a Phasor Measurement based Wide Area Monitoring and Control System was developed and presented. The proposed system emphasizes the need for monitoring and control of transmission lines connected to Distributed Energy Resources. In this work, the modeling for a complete scenario of a Discrete Fourier Transform based Synchronized Phasor Measurement Unit is presented. The...
A method of high performance output voltage control of four-wire inverter based three-phase UPS is proposed. Stationary frame resonant filter bank based output voltage control loop, which is complemented by capacitor current feedback based active damping loop, is employed. Utilizing the zero-state partitioning variable, a generalized form of scalar PWM for the four-wire inverter is developed and the...
