Low-frequency and low-voltage load reduction system based on distributed hierarchical control framework

The invention discloses a low-frequency and low-voltage load reduction system based on a distributed hierarchical control framework. The low-frequency and low-voltage load reduction system comprises at least two execution child stations and a master station, and the execution child stations and the master station communicate in a two-way manner. All the execution child stations are low-frequency and low-voltage load reduction devices arranged in a substation. When the low-frequency and low-voltage load reduction devices detect that the frequency or voltage of a line is lower than a set value, the load of a corresponding round is shed. The master station is composed of an acquisition server and a workstation, wherein the acquisition server counts the low-frequency and low-voltage load shedding capacity sent by the execution child stations and sends the counting result to the workstation for processing, and the workstation sends low-frequency and low-voltage load shedding indicators to the execution child stations through the acquisition server. The dynamic characteristics of the system can be accurately grasped, electrical safety accidents can be avoided, and accurate shedding of load is achieved.
