Marine High-Voltage DC Systems

Model and Simulate Subsea HVDC Link Technologies ETAP HVDC (High-Voltage Direct Current) Link is used to simulate and analyze the transmission of electrical power flow along subsea cables connecting onshore and offshore facilities. HVDC integrated model can be used applications such as load flow, harmonics and transient stability. Multiple control schemes and various types of dynamic operation modes can be included as part of the simulation.
