Islanding Detection of Synchronous Generator-Based DGs using Rate of Change of Reactive Power

The question of the islanding operation of distributed generations (DGs) and that of the current inadmissible networking policy of islanding operations sets a demanding task for an efficient islanding detection, preferably from a single place, using either passive or active islanding-detection method. Islanding detection shall be faster than the fast automatic reclosing of the connected transmission line connected to the DG unit. This paper deals with the detection method of islanded operation mode for the large power synchronous generator-based DGs in bio-mass power plants. The proposed method has been applied to a practical 10-MW bio-mass power plant and experimentally tested to verify the simulation results. The rate of change of reactive power (dQ/dt >) criterion is derived as a yardstick for islanding detection. The practical power plant model has been implemented to be simulated in DIgSILENT PowerFactory and MATLAB/Simulink software environments. Offline digital time-domain simulations and experimental tests on a practical bio-mass power plant reveals that the proposed method efficiently, and authentically detects islanding phenomena with high accuracy, low detection time, very small number of non-detected zones and, with almost zero power balance (ΔP = 0).
