Generalized Dynamic Phasor Modeling of the MMC for Small-Signal Stability Analysis
IEEE Transactions on Power Delivery, 2019This paper introduces a dynamic phasor model of a half-bridge modular multilevel converter based on variables in the stationary ABC frame. The application of the dynamic phasor theory makes it possible to use converter eigenvalues to study the effect of ...

IEEE Transactions on Education, 1967
The concept of transformation is inherent to phasors. This paper puts this concept on a firm basis by defining a phasor transform-pair. The development is parallel to that of Laplace and Fourier transformations, and thus stresses the basic similarity of these transformations in solving linear differential equations with constant coefficients.

Phasor measurements have mainly been applied for transmission systems partly because of cost. There is a continuing reduction in the cost and distribution applications are growing. One of the developing issues is the impact of solar panels in the distribution network causing voltage rises and the potential for battery use to expand.

Design of Phasor Data Concentrator for phasor monitoring system
2012 IEEE Conference on Sustainable Utilization and Development in Engineering and Technology (STUDENT), 2012A Phasor measurement system is used for measuring of the amplitude, phase and frequency of the bus voltage in real time. Amplitude and phase of each station are then compared to calculate the differences. Differences in voltage amplitudes affect the amount of reactive power flow. The active power flow is influenced by differences in the voltage phasors.
