Simple SummaryContent extracted from patent full text and abstract with AI.

The invention describes a safety device and method for monitoring electrical power supply networks using artificial neural networks (ANNs). Unlike traditional protection devices that rely on hard-coded deterministic algorithms, this solution uses deep learning and pattern recognition on graphical representations (like spectrograms) derived from network measurement data. By leveraging image-processing neural networks such as convolutional neural networks (CNNs) and optionally recurrent neural networks (RNNs), the system can more flexibly, quickly, and reliably identify both normal and abnormal operating states, including complex or previously hard-to-detect faults.

Use CasesContent extracted from patent full text and abstract with AI.

  • Real-time fault detection in electrical power grids, including subtle fault types like high-impedance ground faults.
  • Automated monitoring and protection for decentralized or smart grid systems with renewable energy sources.
  • Enhancing substation and transmission line protection schemes.
  • Deployment in both local (on-device, edge) and central (cloud-based) grid monitoring infrastructure.
  • Smart maintenance systems that analyze grid health and anticipate breakdowns before they escalate.

BenefitsContent extracted from patent full text and abstract with AI.

  • Improved detection accuracy, including faults that conventional protective equipment struggles to identify.
  • Self-learning and adaptive capability allows the system to adjust to changing grid configurations or operating conditions without extensive reprogramming.
  • Faster response to faults, reducing outage times and potential equipment damage.
  • Scalable architecture – can be used for single points (local), regional, or grid-wide (central/cloud-based) protection.
  • Hardware-agnostic: can be implemented on various platforms, including embedded devices or cloud servers.
  • Helps increase operational safety, reduce risk of fires or injuries from undetected electrical faults, and support reliable grid operation.

Patent Abstract

Die Erfindung betrifft eine Schutzeinrichtung (22) zum Überwachen eines elektrischen Energieversorgungsnetzes (10), mit einer Auswerteinrichtung (40), die dazu eingerichtet ist, unter Verwendung von Messwerten, die einen elektrischen Zustand des Energieversorgungsnetzes (10) an zumindest einer Messstelle angeben, eine Entscheidung zu treffen, ob sich das Energieversorgungsnetz (10) in einem zulässigen oder einem unzulässigen Betriebszustand befindet, wobei die Auswerteinrichtung (40) ein künstliches neuronales Netz umfasst.Um eine besonders flexible und zuverlässige Möglichkeit zur Erkennung unzulässiger Betriebszustände in Energieversorgungsnetzen anzugeben, wird vorgeschlagen, dass die Auswerteinrichtung (40) dazu ausgebildet ist, zur Entscheidung über den Betriebszustand des Energieversorgungsnetzes eine Mustererkennung einer auf den Messwerten basierenden grafischen Darstellung (G) heranzuziehen.Die Erfindung betrifft auch ein mit einer solchen Schutzeinrichtung (22) ausgeführtes Verfahren zur Überwachung eines Energieversorgungsnetzes (10) sowie ein entsprechendes Computerprogrammprodukt.
