System And Method For Mitigation Of Streaming Electrification In Power Transformers By Intelligent Cooling System Control
US Patent:
5838881, Nov 17, 1998
Filed:
Jul 14, 1995
Appl. No.:
8/502829
Inventors:
John Keith Nelson - Niskayuna NY
John Arthur Palmer - Troy NY
John Arthur Palmer - Troy NY
Assignee:
Electric Power Research Institute, Inc. - Palo Alto CA
International Classification:
G06F 1518
US Classification:
395 22
Abstract:
An intelligent controller for on-line monitoring of circulation system in order to minimize a problem of streaming electrification and to avoid degradation of the electrical insulation of the system. The controller is designed to combine advantages of fuzzy logic and neural networks, and includes a fuzzy logic (employing a pseudo-neural network) for acquiring analog input data from a plurality of sensors and for interpreting this input data into fuzzyfier outputs. A main processor consisting of a fully connected feed-forward neural network serves for processing the fuzzifier outputs in order to obtain controlling instructions for the system.

International Classification:
H02J 3/00, H02P 9/00
US Classification:
322 37, 322 36, 307 32
Abstract:
A system for providing anti-islanding protection of a synchronous machine based distributed generator includes a frequency sensor configured to generate a generator frequency signal, a bandpass filter configured for filtering the generator frequency signal, a governor controller configured for using the filtered frequency signal to generate a power feedback signal, and a governor summation element configured for summing the filtered frequency signal, the power feedback signal, and a reference power to provide an electrical torque signal. Another system includes a voltage sensor configured to generate a generator terminal voltage signal, a feedback power calculator configured for generating a reactive feedback power signal, a bandpass filter configured for filtering the terminal voltage signal, and a PI controller summation element configured for summing the filtered terminal voltage signal, the reactive power feedback signal, and a reference reactive power to provide an error signal.

Additives For Enhancing Corona Stabilization In Electronegative Gases
US Patent:
4410456, Oct 18, 1983
Filed:
Apr 5, 1982
Appl. No.:
6/365722
Inventors:
John K. Nelson - Schenectady NY
Assignee:
General Electric Company - Schenectady NY
International Classification:
H01B 316
US Classification:
252571
Abstract:
Corona stabilization in electronegative gases such as SF. sub. 6 is enhanced through the use of additives exhibiting ionization potentials which lie in the range in which the photon absorption characteristic of the electronegative insulating gas, as a function of ionization energy, exhibits minimal values. Accordingly, the present invention not only discloses such methods for enhancing corona stabilization but also discloses gaseous mixtures exhibiting this enhanced corona stabilization characteristic. Enhanced corona stabilization is important in that it produces significantly increased divergent field breakdown voltages in the gaseous mixture in gas pressure ranges which are of significant interest to the electrical industry. In particular, it is seen herein that tri-ethylamine is a particularly effective additive for use with SF. sub. 6.
Nanostructured Dielectric Composite Materials

Abstract:
A nanocomposite material suitable for electrical insulation includes a polymer compounded with a substantially homogeneously distributed functionalized nanoparticle filler. The nanocomposite material is produced by compounding the polymer with the functionalized nanoparticle filler by imparting a shear force to a mixture of the polymer and filler capable of preventing agglomeration of the filler whereby the filler is substantially homogeneously distributed in the nanocomposite material. The electrical insulation may be adapted for AC or DC high voltage, and may also be adapted for low or medium voltage to prevent formation of water tree structures.
