Popis: | Phasor Measurement Units (PMUs) are widely used in the Smart Grids (SGs). In this paper we propose the discrete-time frequency-gain transducer (DTFGT) and we apply it for PMU implementation. The DTFGT is a general-purpose, short-cycle, leakage-free, computationally feasible, frequency estimator that exploits gain slope of a Finite Impulse Response (FIR) filter frequency response. The proposed PMUs inherit the features of the DTFGT and are compliant in Protective class (P) and Measurement class (M) of the IEC/IEEE 60255-118-1 standard. Comparison with other FIR based PMUs highlights advantages of the proposed solution such as high accuracy, good noise immunity, short response time and simple implementation. |
