An elevator energy management system includes a first variable frequency drive configured to deliver electrical power from a power source to an elevator machine during a first operating condition and to receive regenerative energy from the elevator machine during a second operating condition. The second variable frequency drive is configured to selectively receive regenerative energy from the first variable frequency drive during a second operating condition. At least one energy receiving device is coupled to the second variable frequency drive. The energy receiving device is configured to receive regenerated energy from the second variable frequency drive.
电梯能量管理系统包括第一变频驱动器,该第一变频驱动器构造成在第一操作条件期间将电功率从功率源输送到电梯机械并在第二操作条件期间从电梯机械接收再生能量。第二变频驱动器构造成在第二操作条件期间从第一变频驱动器选择性地接收再生能量。至少一个能量接收装置与第二变频驱动器联接。能量接收装置构造成从第二变频驱动器接收再生能量。
