چکیده

An efficient model has been developed to simulate High Voltage Direct Current (HVDC) Converters in real-time transient simulators. Real time performance of 45 μs per solution step has been achieved for a 12-pulse monopolar converter and 81 μs for the bipolar converter using a single processor Pentium Pro 200 MHz desktop computer. The HVDC converter model is solved simultaneously with the power network. Simultaneous solution makes the model capable of sustained long-time simulation for real time testing of system performance and control functions.

A Current Frequency Component-Based Fault-Location Method for Voltage-Source Converter-Based High-Voltage Direct Current (VSC-HVDC) Cables Using the S Transform

This paper proposes a fault-location method for voltage-source converter (VSC)-based high-voltage direct current (VSC-HVDC) systems. This method relies on the current frequency components generated by faults in the cable, and requires the arrival time of the frequency components at two terminals. The S transform is a time–frequency analysis tool that is superior to the wavelet transform in some...

Efficient and Accurate Multirate Simulation of HVDC Converters in a Partitioned Network Environment

Multirate simulation of electric networks exhibiting a wide variety of time constants decreases the simulation runtimes by exploiting the property of circuit latency. The fundamental idea is to use different integration steps for distinct elements and/or parts of the network according to requirements of accuracy for each element. HVDC converters are ideally suited for latency exploitation since...
