Protection device for monitoring energy supply grid using neural network
The patent application (Publication Number: US20240039269A1) describes a protection device designed to monitor an electrical energy supply grid. The device includes a measured value acquisition device to record electrical states at measuring points and an evaluation device formed as a single neural network. This neural network is trained to perform various protection functions based on the measured values and determine if the grid is in a permissible or impermissible state. The device can classify events, detect fault types, and determine fault locations, with the ability to operate locally or centrally within the grid.
Furthermore, the protection device can be trained using different learning methods, such as deep learning and reinforcement learning, to enhance its classification capabilities. It can be specifically trained for different installation locations and is equipped with a communication interface for calibration parameters. The method outlined in the patent involves acquiring measured values, transmitting them to the protection device, and using the neural network to classify the grid's operating states. The device can be trained to carry out all protection functions together and can operate in a two-stage learning method for local monitoring or a one-stage learning method for centralized monitoring of the energy supply grid.
