The invention discloses a method for calculating an elevator balance coefficient and a detection system, and the method comprises the steps: collecting a three-phase voltage value and a two-phase current value of a three-phase motor, and calculating a voltage phase angle value and a line voltage effective value under a voltage synthesis vector in a two-phase [alpha] [beta] coordinate based on the three-phase voltage value and the two-phase current value; synthesizing a current phase angle value and a line current effective value under the vector by the current; the elevator car running speed and the elevator car running distance are calculated based on the voltage phase angle value; calculating a power factor based on the voltage phase angle value and the current phase angle value; the moment when the elevator car passes through the elevator balance position is recognized based on the elevator car operation distance, and the elevator balance coefficient is calculated based on the operation data when the elevator car passes through the elevator balance position. According to the method, the moment when the elevator car passes through the elevator balance position is calculated through the three-phase voltage value, the two-phase current value and the running distance of the elevator car, and the elevator balance coefficient can be quickly and accurately calculated based on the running data when the elevator car passes through the elevator balance position.
