GNU-Aid: Intelligent computer aided instruction system
Educational applications of computer technology have been under development since the early 1960s. These applications have included scheduling courses, managing teaching aids, and grading tests. The predominant application, however, has bee...
Karnaugh Maps - An artificial intelligence approach
The software developed includes an expert system for the simplification of switching circuit expressions with the help of k-maps. The method has been developed for a four variable k-map. The significance of AI becomes clear when we consider...
An optimization approach to the analysis of generalized learning automata algorithms
Weak convergence methods are used to analyse generalized learning automata algorithms. The REINFORCE algorithm has been analysed. It is shown by an example that this algorithm can exhibit unbounded behaviour. A modification based on constra...
Neural Network Approach to Pisarenko's Harmonic Retrieval Method
Pisarenko's Harmonic Retrieval (PHR) Method Is Perhaps The First Eigenstructure Based Spectral Estimation Technique. The Basic Step In This Method Is The Computation Of The Eigenvector Corresponding To The Minimum Eigenvalue Of The Autocorr...
ACE '90 [front matter]
Conference proceedings front matter may contain various advertisements, welcome messages, committee or program information, and other miscellaneous conference information. This may in some cases also include the cover art, table of contents...
Harmonic modelling of voltage source converters for HVDC stations
Interest in the use of VSCs for HVDC substations is increasing rapidly due to their economical and technical advantages. Most of the work reported in the open literature has been on PWM control and VSC topologies, and in HVDC commissioning,...
Analysis of a robust DC-bus voltage control system for a VSC transmission scheme
This paper proposes a high dynamic digital control scheme for IGBT based VSC HVDC power transmission, i.e. VSC-HVDC system, based on equivalent continuous-time state-space models for the rectifier/inverter actuators, using a nonlinear appro...
Control of HVDC systems operating with long DC cables
This paper studies dynamic aspects of HVDC system operation with long DC cables. The eigenvalue analysis of CIGRE HVDC system with extended DC cable is presented. It is concluded that significant aggravation in the system stability is prese...
Small signal modelling of HVDC transmission systems
An exact small signal linear model of the HVDC converter has been published, and this paper describes two applications of the model. The first application is the calculation of steady state harmonic levels in the presence of unbalanced AC s...
A consideration of stable operating power limits in VSC-HVDC systems
The stable operating-power limits of a small scale HVDC system composed of voltage source converters (VSC-HVDC system) are analyzed with a simple model. The VSC-HVDC system could operate where the AC system must be somewhat larger in capaci...
