Problems solved by technology
At present, the station area only monitors the three-phase voltage, current and other electrical quantity data on the low-voltage side of the distribution transformer, but lacks the monitoring and collection of non-electrical quantities such as the top layer oil temperature and ambient temperature of the distribution transformer body, resulting in the inability to accurately grasp the health of the distribution transformer equipment State, especially the risk level of safe operation of distribution transformers under overload conditions, causing overload damage events of distribution transformers to occur from time to time

The invention discloses a method and system for overload control of a distribution transformer. The method includes the following steps: collecting detection data of the distribution transformer, wherein the detection data of the distribution transformer includes the top oil temperature of the distribution transformer and the ambient temperature; Transformer detection data generates a distribution transformer overload event; a fault risk analysis is performed on the distribution transformer overload event; and a governance strategy associated with the distribution transformer overload event is formulated based on the analysis result of the distribution transformer overload fault risk. Accurately evaluate the overload fault risk level of distribution transformers and formulate scientific and reasonable overload management strategies by collecting data such as distribution transformer equipment status, operating status, and environmental status.
Description
technical field [0001] The invention belongs to the technical field of power distribution and utilization, and in particular relates to a method and system for controlling the overload of a distribution transformer. Background technique [0002] The safe operation of distribution transformers is crucial to the reliable power consumption of low-voltage users in the Taiwan area. At present, the station area only monitors the three-phase voltage, current and other electrical quantity data on the low-voltage side of the distribution transformer, but lacks the monitoring and collection of non-electrical quantities such as the top layer oil temperature and ambient temperature of the distribution transformer body, resulting in the inability to accurately grasp the health of the distribution transformer equipment State, especially the risk level of safe operation of distribution transformers under overload conditions, resulting in frequent occurrence of distribution transformer over...
