The utility model relates to an anti -electricity -theft technical field of electric power system especially relates to anti -electricity -theft algorithm and verifies the device, specifically is a massive quantity power supply steals electrical analogue and platform is verified to anti -electricity -theft algorithm. The problem of the device verified can be carried out to anti -electricity -theftalgorithm to the shortage is solved. This platform includes that programme -controlled current generator, primary current steal electrical analogue module, a current transformer, the 2nd current transformer, programme -controlled voltage generator, primary voltage and steal electrical analogue module, a voltage transformer, the 2nd voltage transformer, secondary voltage and steal electrical analogue module, three -phase three -wire primary current 0, primary current 1 and steal electrical analogue module, computer and primary current 2. The utility model discloses a principle of virtual worksupplies power to massive quantity power supply metering device, and the consumed energy is very little, open anti -electricity -theft algorithm verifies and is favorable to developing of anti -electricity -theft algorithm research that it does not have the defect of verifying the platform to have compensatied anti -electricity -theft algorithm.
