Factory power supply network power consumption condition intelligent monitoring system and method

Abstract

The invention relates to the technical field of power monitoring, and provides an intelligent monitoring system and method for the power utilization condition of a factory power supply network, and the system comprises a current collection unit, a monitoring unit, at least one transformer, at least two protection switches electrically connected with the secondary side of the transformer, at least one first power utilization device, and at least one second power utilization device. The current acquisition unit is used for acquiring the real-time current of the secondary side of the transformer, and the monitoring unit is used for controlling at least one protection switch corresponding to the first electric equipment to execute a tripping action when the real-time current of the secondary side of the transformer is not less than an alarm tripping value, so that the real-time current of the secondary side of the transformer is less than the alarm tripping value. And when the real-time current of the secondary side of the transformer is smaller than the alarm tripping value, the protection switches in the tripping state are driven one by one according to a first limiting formula to execute reclosing action. It can be guaranteed that the secondary side output current of the transformer is smaller than the alarm tripping value, and automatic and intelligent monitoring of a factory power supply network is achieved.

Description

technical field [0001] The invention relates to the technical field of power monitoring, in particular to an intelligent monitoring system and method for power consumption of a factory power supply network. Background technique [0002] In factories, transformers are generally used to drive multiple electrical equipment. Among the multiple electrical equipment, there are often key equipment with a relatively heavy load (such as a grinder in a ceramic factory) and core equipment with a relatively small load (such as a kiln in a ceramic factory). The core equipment cannot be powered off casually, otherwise it is easy to cause a complete shutdown of the production line, which will bring immeasurable losses to the factory. [0003] In existing factories, in order to ensure the normal operation of core equipment and ensure that the production line does not stop, managers often selectively suppress and reduce the commissioning of key equipment based on experience to avoid serious...
