Abstract

The invention discloses a control system integrating elevator control, driving and energy feedback. The control system comprises an elevator logic control module, an elevator motor motion control module and an energy feedback module, wherein the elevator logic control module is used for elevator collective selective control, parameter testing and storing, elevator fault clearing and system self-checking and processing; the elevator motor motion control module is used for detecting the speed of an elevator motor, detecting a motor electric angle, generating an elevator running curve and controlling the elevator speed, acceleration and torque; the energy feedback module adopts dual pulse-width modulation (PWM) control technology; a controlled reactor is arranged between the input end of a three-phase power supply and a first intelligent power module (IPM); and the input current of an elevator and the current and rotating speed of a driving motor are calculated accurately so as to fulfill the aims of accurately controlling the elevator speed and acceleration and feeding energy back to a power grid. An energy-saving elevator control system can be realized due to the adoption of the control system.

Description

technical field [0001] The invention relates to an elevator system, in particular to a control system integrating elevator control, drive and energy feedback. Background technique [0002] With the continuous expansion of modern production scale and the continuous improvement of people's living standards, the contradiction between power supply and demand has become increasingly prominent, and the call for power saving has become increasingly louder. At the same time, domestic and foreign elevator manufacturers have also begun to pay attention to the energy-saving issue of elevators. For example, the elevator drive host is changed to a permanent magnet synchronous motor, etc., and a very small number of elevators are equipped with energy feedback devices. However, because the control algorithm of the energy feedback devices installed is not advanced, the product quality is unstable, and the electric energy fed back has a great impact on the grid and Other electrical equipment...
