A new voltage instability detection index based on real-time synchronophasor measurements.

Chappa, H. K. and Thakur, T. and Kazemtabrizi, B. (2016) 'A new voltage instability detection index based on real-time synchronophasor measurements.', in 2016 IEEE 16th International Conference on Environment and Electrical Engineering (EEEIC) : 7-10 June 2016, Florence, Italy ; proceedings. , pp. 1-5.


This paper demonstrates the performance of the Reactive Power Loss Based Voltage Instability Detection Index (QLVIDI), previously introduced in [1], under various testing conditions applied to the New England 39 bus test system using time-based simulations in the Power System Analysis Toolbox (PSAT) in MATLAB. The proposed scheme calculates an instantaneous time series of reactive power losses taking into account the direction of active power flow in every node in the system by considering the reactive power limits of the generators. This time series data is then used to evaluate a cumulative reactive power loss and the degree of deviation from the base case loss for developing QLVIDI. The effectiveness of the proposed index in early detection of imminent voltage collapse scenarios has been tested in various cases and also compared with already existing Improved voltage instability monitoring index(IVIMI).
