摘要： Retard energy regenerated from an electrical motor during braking action is reinjected into a power system via trolley lines. The retard energy may be transmitted to a bidirectional electric substation and returned to a utility grid. The retard energy may also be transmitted to an auxiliary energy storage system, such as an ultracapacitor system or a battery system. Installing trolley lines for mining haul trucks on a downhill slope may be used to capture and re-use substantial quantities of retard energy.

摘要： Braking current generated by an electrical motor on mining equipment during a retard interval is switched through one or more grid resistors that are liquid cooled. Under low ambient temperatures, a heating current can be switched through the grid resistors when the electrical motor is not operating in a retard interval. An integrated cooling system can be used to cool grid resistors and power modules. Heat dissipated by the grid resistors and the power modules can be circulated through auxiliary heating loops to heat portions of the mining equipment under low ambient temperatures. Multiple liquid-cooled power modules, liquid-cooled grid resistors, auxiliary heating loops, control modules, radiators, and pumps can be coupled by a liquid distribution system with various combinations of parallel and serial branches. Temperature, pressure, and flow rate in each branch can be independently controlled. Operation of the integrated cooling system can be controlled by a computational system.

摘要： High-power synchronous motors are commonly used in mining operations, for example, in gearless draglines, gearless conveyor drives, and gearless mill drives. Substantial electromagnetic energy is stored in the inductive field windings. In the event of a system fault, such as a short in the direct current power source exciting the field windings, the electromagnetic energy needs to be discharged from the field windings. This electromagnetic energy is typically dissipated as waste heat through a resistor. Disclosed is a field discharge system in which the electromagnetic energy is captured and stored as electrical energy in a capacitor. If an ultracapacitor bank is used for storage, the charged ultracapacitor bank can be used as a backup or auxiliary power source for mining operations. The discharge time is sufficiently small that high speed circuit breakers are not needed to disconnect stator windings from the alternating current power source when a fault occurs.
摘要翻译：大功率同步电动机通常用于采矿作业中，例如无齿轮拖拉机，无齿轮输送机驱动装置和无齿轮磨机驱动装置。电磁场绕组中存在大量电磁能。在发生系统故障的情况下，例如直流电源短路励磁绕组，电磁能需要从励磁绕组放电。这种电磁能量通常通过电阻器作为废热消散。公开了一种场放电系统，其中电磁能被捕获并作为电能存储在电容器中。如果超级电容器组用于存储，则充电的超级电容器组可用作采矿作业的备用或辅助电源。放电时间足够小，因此当发生故障时，不需要高速断路器将定子绕组与交流电源断开。
