    • A power management system for a plant electrical network using plurality of controllers configured for power management such that a first controller from the plurality of controllers is configured to perform power management in a first local process area within the plant electrical network and is capable to communicate with a second controller that is configured for power management in a second local process area within the plant electrical network over a plant wide communication network. The power management function in the first local process area is performed based on the information communicated between the first controller and the second controller or/and based on power balance computation carried out for plant wide electrical network or that for the first local process area. The power management function includes slow load shedding to control load condition in power equipment in the plant electrical network. The method for power management and slow load shedding are provided along with the controller for carrying out power management function in the plant electrical network.
    • 一种用于工厂电气网络的电力管理系统,其使用配置用于电力管理的多个控制器,使得来自所述多个控制器的第一控制器被配置为在所述电厂电网内的第一本地处理区域中执行电力管理,并且能够与 第二控制器,被配置为通过工厂宽通信网络在工厂电气网络内的第二本地处理区域中进行功率管理。 基于在第一控制器和第二控制器之间传送的信息,或者基于对于工厂宽电网进行的功率平衡计算,或者对于第一本地处理区域进行功率平衡计算,执行第一本地处理区域中的电力管理功能。 电源管理功能包括缓慢负载脱扣,以控制工厂电网中电力设备的负载状况。 电力管理和缓慢负载脱落的方法与控制器一起提供,用于在工厂电网中执行电源管理功能。
