Energy Regeneration Technology Applied Research On The Escalator

Escalator had been applied more and more widely in public places because of its transport capacity strong and comfort. Because of the great power consumption, escalators and energy conservation technology is a great deal of attention to the current domestic escalator control system mostly or only the ordinary frequency conversion technology, in order to reduce the no-load speed to achieve the goal of energy saving. But the technology products, overloading downward when braking resistance is still need to add to the feedback energy consumption, not only waste the energy, reach the maximum energy saving, large volume of brake resistance has increased in installation. In this century with the development of power electronic technology, energy regeneration technology has been developing, has already started in many fields of mechanical and electrical applications. In escalator industry, the current is braking resistor is used to complete the downward load motor power generation mode the energy generated at runtime, the emergence of energy regeneration frequency converter to replace the function of braking resistor, the mechanical energy is converted into accord with alternating current feedback to the power grid, the national standard of the Internet to achieve maximum reduce the power consumption of escalator running, reduce braking resistance of thermal pollution, is the development direction of saving energy and reducing consumption escalator field.This topic mainly introduced the escalator status quo and development of energy-saving technology, and through the theoretical analysis of energy regeneration frequency converter, illustrates the advantage of energy regeneration frequency. The energy regenerative inverter is studied mainly electronic components selection method, the selection of main circuit parameters and design method, the choice of the fuse, and the parameters of the LCL filter, measuring circuit for IGBT hardware implementation and so on has carried on the detailed analysis and design; Then renewable energy converter in the application of the escalator to do the research, finally completed the renewable automatic ladder control design and testing. Energy regeneration frequency conversion system working principle is: when the load downward escalator load, will be transformed into mechanical energy through the motor ac feedback back to the electricity grid, realize the energy regeneration and utilization. For energy conservation today, the use of the renewable escalator control system in the escalator industry application prospect.After efforts, has been complete energy regeneration type escalator control system design, the system started in the company S current mainstream products on the integrated application. Through the sample system functional test and reliability test and field application show that the system design is reasonable, the factory site work stability, performance meet the national standard research and development of the desired goal.
