摘　　要：针对下运带式输送机在重载输送时会产生再生电能的特殊工况,提出了回馈制动系统的应用。对回馈系统的原理进行了阐述,并提出了一种高效可行的控制方法,采用空间矢量脉宽调制策略生成IGBT开关信号,实现了再生电能安全有效地回馈至电网。运用仿真软件Simulink对能量回馈系统进行了仿真,结果表明:回馈系统实现了再生电能以单位功率因数回馈电网,证明了系统的可行性。Aiming at the special working condition of downward belt conveyor in heavy-load transportation,which will produce renewable energy, the application of the regenerative brakihg system is proposed. The working principle of the system is expounded, and a high-efficient and feasible control method is put forward. Then apply space vector pulse width modulation （SVPWM） strategy to produce switch signal, which determines the make and break of IGBT to control the regenerative energy recycled to power grid efficiently. Simulation software Simulink is used to simulate the energy feedback system. The simulation results show that the designed energy feedback system realizes unity power factor energy feedback to the power grid, and it proves the application of the control system is feasible.
