An electrical power distribution system has at least one converter module having a converter, which is designed to convert AC voltage from one or more AC voltage sources to DC voltage and provide DC voltage power with adjustable maximum power values at a plurality of electrical output interfaces of the converter module up to a maximum module power value. The power distribution system also comprises a power profile management device, which is coupled to the converter and is designed to negotiate individual power profiles with electrical consumers that can be connected to respective ones of the plurality of electrical output interfaces, according to which individual power profiles electrical power up to a negotiated maximum power value is provided to the consumers by the converter via the electrical output interface and which are stored in a power profile memory of the power profile management device. The power profile management device is configured to detect the instantaneous actual power consumption of the connected consumers with which an individually negotiated power profile already exists, to calculate for each individually negotiated power profile a power reserve value of the converter as the difference between the negotiated maximum power value and the instantaneous actual power consumption, and to negotiate with one or more of the electrical consumers whose power reserve value is higher than an adjustable reserve threshold value a new power profile with a maximum power value lower than the negotiated one if the sum of the negotiated maximum power values exceeds the maximum module power value.
一种电功率分配系统具有带有电流转换器的电流转换器模块,电流转换器设计为将交流电压源的交流电压转换为直流电压并将具有可设定功率最大值的直流电压功率提供给电流转换器模块的电输出接口直至模块功率最大值。功率分配系统还包括与电流转换器联接的功率配置管理装置,其被设计为与连接到电输出接口中的相应电输出接口处的耗电器协商单独的功率配置,电流转换器根据功率配置经由电输出接口为耗电器提供电功率直至经协商的功率最大值,功率配置被存储在功率配置管理装置的功率配置存储器中。功率配置管理装置被配置为:检测已存在经单独协商的功率配置的所连接的供电器的瞬时实际功率输入;对每个经单独协商的功率配置作为经协商的功率最大值与瞬时实际功率输入之差来计算电流转换器的功率保留值;当经协商的功率最大值的总和超过模块功率最大值时,与功率保留值高于可设定保留阈值的耗电器中的一个或多个协商新功率配置,新功率配置具有的功率最大值小于经协商的功率最大值。
