Abstract

Disclosed are a measurement method and measurement circuit for a power parameter. The measurement method comprises: adjusting the size of conduction angles, and acquiring (102) a maximum voltage waveform value of a live line end or a load end at different conduction angles; dividing (103) the maximum voltage waveform value at different conduction angles by a standard maximum waveform value of a corresponding conduction angle acquired at a standard voltage to obtain a voltage ratio at different conduction angles; according to the voltage ratio, acquiring (105) voltage effective values and active power at different conduction angles; according to the voltage effective values and current effective values at different conduction angles, acquiring apparent power at different conduction angles; and finally, controlling the current effective values, the voltage effective values, the active power and the apparent power to display for user reference. Power parameters can be calibrated according to voltage ratios obtained at different conduction angles, and power parameters can be accurately acquired. Moreover, a user can directly observe real-time power parameters, thereby being convenient for a user to use.
