Frequency stability and voltage stability have mutual influence on each other. Conventional load shedding control strategies generally apply Underfrequency Load Shedding (UFLS) and Undervoltage Load Shedding (UVLS) respectively without considering time-space distribution characters of voltages and dynamics of induction motors. Based on the two-node model of the power system, this paper analyses the...
Conventional load shedding control strategy adjusts undervoltage load shedding and underfrequency load shedding respectively, and undervoltage load shedding only focuses on local voltages without consideration on characters of transient voltage responses. This paper analyses the relationship between the disturbance scale and transient voltage drops, thus proposing a novel index for the disturbance...
A DFIG-based wind generator electromagnetic transient model is established on the RTDS platform in this paper. Stator flux oriented vector control scheme is adopted to achieve power decoupling control in the DFIG based wind model. In order to research the impact of the wind farm on the existing protection relay of the network, this paper establishes single machine electromagnetic dynamic equivalent...
Dynamic voltage stability analysis is mainly based on the time-domain solution of power system differential equations. The modeling of each power element has a great influence on the correctness and complexity of stability analyzing. It is a significant work to model appropriately for simplifying calculation and drawing out principal contradiction. Firstly, the dynamical mechanism of voltage stability...
