Abstract:
The method for determining mutual voltage sensitivity coefficients between a plurality of measuring nodes (M1,..., M7) of an electric power network (1) does not rely on knowledge of the network parameters (for example: series conductance and susceptance of the branches, shunt conductance and susceptance of the nodes, etc.). The method uses a monitoring infrastructure comprising metering units at each one of the measuring nodes, and it comprises a step of measuring at the same time, at each one of said measuring nodes (M1,..., M7), repeatedly over a time window ( τ ), sets of data comprising values of the current ( Ĩ (t)), the voltage ( V (t)), and the phase difference ( φ ( t )), a step of computing active power ( P ( t )) reactive power ( Q ( t )) values from each set of measured data, and a step of performing multiple parametric regression analysis of the variations of the voltage at each one of the measuring nodes.
