| Abstract |
This paper examines a technique for on-line measurement of power system supply impedance. The
method employs a power electronic inverter to apply a short duration transient onto the energised
power network. The voltage disturbance and the consequent current transient are measured and may
be used to identify supply impedance. Experimental results demonstrate the effectiveness of the
technique for identification of the impedance of transmission lines and linear loads. The performance
of this method is also examined in the presence of non-linear loads. An alternative data processing
method is introduced in order to improve the technique and to compensate for the measurement
problems associated with non-linear loads. This is also verified experimentally. |
