The AutomationSolution for Photovoltaic Power Systems serves as the core technical framework to ensure the safe, stable, and efficient grid-connected operation of power plants. This solution for grid-connected photovoltaic power systems must adhere to the fundamental principles of power system…
Project Background Our Hydropower Plant Upgrade Solution targets Vietnam, one of Southeast Asia’s fastest-growing hydropower markets. Boasting over 1,500 small and medium hydropower stations, the country urgently needs high-quality, reliable protective relay solutions to secure safe operation of generators, transformers…
Intelligent motor protection relays, also known as electric motor protection relays, provide vital motor protection functions. When abnormal conditions including overload, phase loss, locked rotor, short circuit, overvoltage, undervoltage, earth leakage, three-phase imbalance, overheating, bearing wear and stator-rotor eccentricity occur…
Principle of Transformer Differential Protection The basic principle of differential protection adopted by protection relays for transformer and relays for transformer protection is to compare the magnitude and phase of currents on both sides of the transformer. Under normal operating…
Photovoltaic solar power systems (solar photovoltaic power systems) convert sunlight into electricity via photovoltaic panels; the generated power is either fed into the grid through inverters or stored in batteries. Composed of photovoltaic modules, combiner boxes and inverters, these systems…
A generator synchronization panel is dedicated to the synchronous grid connection of generators or busbars with the power system. It monitors the voltage, frequency and phase of the power system, the incoming generator and the busbar. Meanwhile, it can adjust…
