This paper presents a feasibility study of an offshore wind farm (OWF) HVDC integration system using high-temperature superconductor (HTS) DC cables. A representative ±100 kV/2 GW point-to-point OWF is proposed including HTS cables and two converter stations modular multilevel converters (MMCs). To be compatible with the high current rating cables, each onshore consists three MMCs in parallel. ...

Navy shipboard power systems have different characteristics when compared to utility power systems. To conduct system studies on shipboard power systems, an effective simulation tool is required to model shipboard electric power systems. PSpice is a very powerful tool for analog/digital circuit simulation, but it is rarely used for power systems. This paper presents modeling shipboard power sys...

A novel servomotor design that is powered and controlled through only one wire is presented in this paper. A traditional servomotor needs both a power cable and a control cable connecting the motor to a control amplifier. Cables are bulky, heavy, and expensive and, more importantly, difficult to install and maintain in many applications. Particularly for multi-axis applications, like robots and...

With the large scale developments of offshore windpower the number of underwater electric cables is increasing with various technologies applied. A wind farm is associated with different types of cables used for intraturbine, array-to-transformer, and transformer-to-shore transmissions. As the electric currents in submarine cables induce electromagnetic fields there is a concern of how they may...

Communication is the method by which two persons can share any meaningful information with each other at an instant. It requires a sender who wants to communicate, message which is to be conveyed & receiver who receives this message at the receiver end. Now a days due to the advancements and technology, digital communication is receiving wide attention among researchers. Digital communication i...

Accurate, real-time information about the aging status of the power distribution cable network can save the power industry millions of dollars lost due to line failures and premature replacement of cables. Hence, a novel, semiautonomous robotic sensor platform has been developed for monitoring underground, power distribution cable systems. A segmented, legged modular configuration allows the ro...

Partial discharge (PD) detection is an important means in the condition-based maintenance of high voltage apparatus including crosslinked polyethylene (XLPE) power cables. In this contribution, we introduce the recent work in Shanghai municipal electric power company on the condition-based maintenance of XLPE power cables. As to how to carry out the PD detection in different circumstances, thre...

Short-circuit calculations are extremely important in the application and setting of protective relays and the analysis of power system operations. This paper illustrates the calculation of fault currents and voltages during intermediate faults in underground cables, taking into consideration the cable sheath bonding and grounding method. The compensated ground loop impedance for faults along t...
