摘要：
This paper proposes a methodology to estimate equivalent inertia in large power systems based on measurements provided by Phasor Measurement Units (PMUs). Considering the availability of PMUs spread on the system, the Ward equivalent method is proposed to reduce the system around the measurement points, and dynamic equivalents are built around the selected buses. Simulations are performed with a 65-bus, 16 generators test-system to provide synthetic data for the application of the proposed method, and results considering two study cases are presented to illustrate and validate the approach.
