Abstract

The embodiment of the invention provides a power management method, which comprises the following steps: receiving first information associated with a group of slave modules coupled with a master module of equipment, the first information at least indicating the working power of each of the group of slave modules in a normal working mode; receiving second information associated with a power supply, the power supply configured to supply power to the master module and the set of slave modules; calculating the sum of working powers of the group of slave modules based on the first information; determining a power limit value based on the second information; and if the sum of the working power of the group of slave modules is not greater than the power limit value, sending an instruction for changing the working mode to the group of slave modules, so that the group of slave modules is converted from the low-power-consumption working mode to the normal working mode. The invention further provides a corresponding control device and electrical equipment. According to the scheme, module management and power management of the modular electrical equipment can be effectively improved, and the performance of the electrical equipment is improved.

Description

Technical field [0001] Embodiments of the present disclosure relate to power management, more particularly related to modular controllers and their power management. Background technique [0002] In the electrical system, some controllers are widely used for implementing specific control functions. For example, the power conversion controller used in the scenes such as building residential, factory, and automation production line can determine if the power source is valid based on the voltage, frequency, unbalanced equrometal parameters of the main power source and the backup power source, and for example, if the main The power supply failed, the dual power conversion controller can drive the related device to convert the power supply in the above scenario from the main power source to the standby power. [0003] In recent years, as the needs of users is increasing, the auxiliary function of the controller in the electrical system is more and more diverse. Taking the power conver...
