Method for detecting a defective measurement of an extensive electrical quantity
First Claim
1. A method for detecting a faulty measurement of at least one extensive electric quantity of an electric network comprising an upstream supply and at least two downstream outlets, the supply and the outlets being each provided with a sensor for measuring the extensive electric quantity, each sensor conducting, in a synchronous way with other sensors, a measurement of the extensive electric quantity depending on a parameter p, the method comprising:
- performing at least N measurements of the value on the upstream supply and on each downstream outlet conducted for different values of the parameter p, and once the measurements have been performed;
a) formalizing a relationship between the measurements, for each value of parameter p with equation;

Abstract
In an electric network (1) which comprises an upstream supply (2) and at least two downstream outlets, the supply and the outlets are each provided with a sensor (6) for measuring an extensive electric quantity and each sensor conducts, in a synchronous way with the other sensors, a measurement of this quantity depending on a parameter. This method comprises at least N measurements of the value on the upstream supply and on each downstream outlet conducted for different values of the parameter p. Then, the relationship between the measurements is formalized, for each value of the parameter p with the equation:
A system with N equations and N unknowns is generated, the unknowns being the gains ai, the system of equations is solved, by calculating each gain, and the gains are controlled. If all the gains are equal to 1, it is considered that no sensor has conducted a faulty measurement. If at least one of the gains is different from 1, it is considered that at least one sensor has conducted a faulty measurement.
