Abstract
Power estimation method, implemented in a three-phase electricity meter, includes the steps of detecting a fraud which falsifies measurements of a first phase voltage present on a first phase, without falsifying measurements of a second phase voltage present on a second phase; reconstituting first estimated voltage samples, images over time of the first phase voltage, from second voltage samples, images over time of the second phase voltage; and estimating at least one first electrical power consumed on the first phase by using the first estimated voltage samples.
Claims15
A power_estimation method, implemented in a three-phase electricity meter, and comprising the steps of:
- detecting a fraud which falsifies measurements of a first phase voltage present on a first phase of a distribution network, without falsifying measurements of a second phase voltage present on a second phase of the distribution network;
- reconstituting first estimated voltage samples, images over time of the first phase voltage, from second voltage samples, images over time of the second phase voltage, the second voltage samples being offset over time by an expected theoretical phase shift without fraud between the first phase voltage and the second phase voltage;
- estimating at least one first electrical power consumed on the first phase by using the first estimated voltage samples.
