Author-Neural Network module

Description

Provides the Neural Network Toolbox for Scilab.

ideas

There are several libraries. From these two main libraries, the library can be distinguished:

FANN: C library that implements the classic neurals networks and actively developed. For version 3, FANN will include recurrent neural networks, several accelerated neural networks (based on Blas or the GPU). It runs on Windows, Unix, MacOS;
SNNS: a tool with a graphical interface. This tool implements nearly all know neural networks (current, SOM, etc. ....etc

ABSTRACT
Urban electrical power systems with steep demand increase need easily located solutions with short lead time from decision to transmission. While AC cable solutions can offer sufficient power ratings, the problems of load controllability and short circuit power increase with every added circuit. These problems may be countered with Voltage Source Converter (VSC) based technology using Cables for transmission, such as HVDC Light. This technology offers up to 500 MW per station with small footprint, ideal for in feed to city centers. ....etc

BASIC HVDC AND CONVERTER OPERATION



Why HVDC rather than HVAC?
Long distances make HVDC cheaper
Improved page link stability
Fault isolation
Asynchronous link

Inverter operation ( = 140 )
Firing is delayed so much that the entire area enclosed between the voltage waveform and the zero line is of opposite polarity.

The equation written in terms of is still correct:

Vd=Vdio -0.766-Id. Xc+Er
2
Vd=-Vdio x 0.8609
However this is usually written in t ....etc

Voltage Source Converter (VSC) based HVDC transmission systems are available in market for power rated between a few MVA to a few hundreds of MVA. The new system results in many application opportunities and new applications in turn bring up new issues of concern. This paper aims at exploring the HVDC transmission systems and also presents a comprehensive investigation on one of the concerned issues, which is the contribution of HVDC Light? to short circuit currents. Different AC network conditions, load conditions and fault types are considere ....etc

A converter transformer is a main component in the HVDC transmission system. The converter transformer failure is the major cause of worry of electric power utilities. It is the top portions of the secondary windings of the converter transformers that fail leaving the primary winding unaffected. In this article, a practical HVDC system has been modelled to find the the causes for these failures. The MATLAB/SIMULINK environment has been used as the modelling environment. The possible solutions that emerged include providing passive filters on t ....etc

Adaptive Network Based Fuzzy Inference Systems (ANFIS)



ANFIS is an adaptive network. An adaptive network is network of nodes and directional links. Associated with the network is a learning rule - for example back propagation. It s called adaptive because some, or all, of the nodes have parameters which affect the output of the node. These networks are learning a relationship between inputs and outputs.
Adaptive networks covers a number of different approaches but for our purposes we will investigate in some ....etc

introduction
the controller always aims to achieve the process variable to the
given set point value. this is the main task of the properly
designed controller. the controller should also provide some
flexibility in case of change in set point and disturbances. today
there are many methods for designing intelligent controllers, such
as predictive controller, fuzzy control, neural networks and expert
systems. various combinations of these controllers give a number
of design possibilities.
