This application provides a substation measurement and control device and method with data verification and abnormal alarm functions, wherein the device includes: a flow screen, a calibrator, a classifier and a diagnostic module; The data information unit is used to calculate the data flow of the received substation data information and control the flow threshold of the substation data information; the verifier is connected to the flow screen to detect the data flow, if the detected data flow is greater than the preset If the flow alarm threshold is exceeded, an abnormal flow alarm will be issued; the classifier is connected to the flow sieve to receive the substation data information after flow threshold control, and to classify different types of information in the substation data information; the diagnostic module is connected to the classifier for Abnormal diagnosis for different types of information is carried out on the classified substation data information. The application can provide support for the reliable operation of the intelligent substation automation system.
Description
technical field [0001] The invention relates to the technical field of substation measurement and control, in particular to a substation measurement and control device and method with data verification and abnormal alarm functions. Background technique [0002] The substation measurement and control device is the core equipment of the substation automation system and the core node of the "four remotes". It is responsible for the collection and transmission of remote signaling and telemetry data, as well as the reception and forwarding of remote control and remote adjustment data. Therefore, it can also be said that the measurement and control device is a key hub for data collection, processing and forwarding of the substation automation system. The accuracy and reliability of the data are of vital significance to the normal operation of various functions of the measurement and control device. [0003] The current measurement and control devices do not have data verification ...
