Redundancy Determination of HVDC MMC Modules
An availability and a reliability prediction has been made for a high-voltage direct-current (HVDC) module of VSC (Voltage Source Converter) containing DC/DC converter, gate driver, capacitor and insulated gate bipolar transistors (IGBT). This prediction was made using published failure rates for the electronic equipment. The purpose of this prediction is to determinate the additional module re...
متن کاملDesign of a Robust Nonlinear Fuzzy Controller for HVDC Systems
The design and stability assessment of a new robust nonlinear fuzzy controller that may be applied in the control loops of HVDC systems is presented. A new simplified nonlinear dynamic model is developed for HVDC systems that can be used to design the controller. The proposed model decomposes into several linear systems around important equilibrium points. These local linear models describe the...
متن کاملDesign of a Hvdc-based Controller for Load Change Compensation and Stabilization of Inter-area Oscillations
As an interconnected power system via a High-Voltage Direct Current (HVDC) link is subjected to a rapid load change with the frequency of inter-area oscillation mode, system frequency and tie line power may be severely disturbed and oscillate. To compensate for the rapid load change and stabilize both frequency and tie line power oscillations due to the inter-area mode, the dynamic power flow c...
متن کاملNeural Controller Design for Suspension Systems
The main problem of vehicle vibration comes from road roughness. An active suspension systempossesses the ability to reduce acceleration of sprung mass continuously as well as to minimizesuspension deflection, which results in improvement of tire grip with the road surface. Thus, braketraction control and vehicle maneuverability can be improved consider ably .This study developeda new active su...
متن کاملComparison of Pi and Ann Controller for Hvdc Link
This paper presents the HVDC system for power system to control the power flow between two converter stations. In this paper, rectifier side is used to control current and inverter side is used to control current as well as extinction angle. In power control system, proportional-integral (PI) controller is widely used. Here we compare its performance with conventional controller and artificial ...
