Home / Relay Protection of Prefabricated Substations
Relay protection is essential to ensure the stability, reliability, and safety of electrical power systems. Apply advanced protection and monitoring with flexible communications to two-, three-, and four-terminal transformers. Protect and control grounded and ungrounded, single- and double-wye capacitor bank configurations. Generator protection covers: phase-to-phase short circuits in stator windings, stator ground faults, inter-turn short circuits in stator windings, external short circuits, symmetrical overload, stator overvoltage, single- and double-point grounding in the excitation circuit, and loss of excitation. This study introduces a new diagnostic framework that combines improved particle swarm optimization, K-means clustering algorithms, support vector machine (SVM), and learning vector quantization neural networks to provide a comprehensive fault diagnosis and pre-diction model for relay protection.
The prefabricated substation''s development trend is towards digitization, intelligence, integration, network, which requires it must put together such functions as protection, measurement, control,
