Dc Power Regulator Incorporating High Power Ac To Dc Converter With Controllable Dc Voltage And Method Of Use

View page
US Patent:
6433520, Aug 13, 2002
Filed:
May 29, 2001
Appl. No.:
09/867165
Inventors:
Colin David Schauder - Murrysville PA
Assignee:
Siemens Power Transmission Distribution Inc - Wendell NC
International Classification:
G05F 306
US Classification:
323207
Abstract:
A high power dc power regulator utilizes a voltage sourced inverter connected on the ac side in series with a large inductance to an ac power system through a coupling transformer. The dc side of the inverter is connected to the dc load. The inductance is sized such that the voltage at the ac terminals of the inverter can be varied from zero to a maximum specified value for use, for example, in melting ice on transmission lines. As there is only infrequent need for ice melting operation, the large inductance can be shunted and the dc load disconnected so that the inverter may be operated for the majority of the time as a conventional STATCOM to provide reactive compensation for the ac power system.

Slip-Controlled, Wound-Rotor Induction Machine For Wind Turbine And Other Applications

View page
US Patent:
7554302, Jun 30, 2009
Filed:
Sep 14, 2006
Appl. No.:
11/521426
Inventors:
Colin David Schauder - Murrysville PA, US
Assignee:
SATCON Technology Corporation - Boston MA
International Classification:
H02P 9/00
H02P 9/10
US Classification:
322 44, 322 59
Abstract:
A system and method for providing constant-frequency electrical power from variable-speed mechanical power are disclosed. The system includes a wound-rotor induction machine generator (WRIMG), a first power converter, e. g. , an inverter or a bridge rectifier, that provides power from the stator assembly of the WRIMG to the load, and a second power converter, e. g. , an inverter or a bridge rectifier, that provides power from the rotor assembly of the WRIMG to the load. A controller controls the output stator-current based on comparisons between measured DC load bus data and a reference DC load bus voltage value, measured machine shaft angular position and reference rotor frequency data, and measured stator-current data that is fed-back to the stator-current controller by the power converter device(s).

Automatic Ac Bus Voltage Regulation For Power Distribution Grids

View page
US Patent:
20120105023, May 3, 2012
Filed:
Oct 27, 2010
Appl. No.:
12/913633
Inventors:
Colin David Schauder - Murrysville PA, US
Leo F. Casey - Lexington MA, US
Assignee:
SATCON TECHNOLOGY CORPORATION - Boston MA
International Classification:
G05F 1/70
US Classification:
323207
Abstract:
A system for automatically regulating voltage on a distribution-level AC bus having an actual voltage and a nominal voltage includes an electronic power converter connected to the distribution-level AC bus. The system generates a feedback signal representative of the actual voltage of the distribution-level AC bus and produces an input control signal in response to the feedback signal. The input control signal is representative of a commanded level of reactive power. The electronic power converter is responsive to the input control signal to deliver a commanded reactive power output to the distribution-level AC bus, and the commanded reactive power output pushes the actual voltage towards the nominal voltage.

Hidden Dc-Link Ac/Ac Converter Using Bilateral Power Switches

View page
US Patent:
46427511, Feb 10, 1987
Filed:
Feb 14, 1986
Appl. No.:
6/829739
Inventors:
Colin D. Schauder - Murrysville PA
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
H02M 522
US Classification:
363159
Abstract:
The invention resides in providing bilateral switches between the respective phase lines of an AC input source and a common phase line of an AC output to form a phase line group of said bilateral switches on each AC output line; in fact, controlling the bilateral switches of each group so as to generate with AC input lines a DC link voltage with respect to the associated AC output line, and secondly in controlling the bilateral switches in such group to modulate such DC link voltage in relation to a desired AC voltage for such associated AC output line, each of said groups being operated with a corresponding phase shift to provide a corresponding phase shift between the respective output phase lines.

Series Compensator Inserting Real And Reactive Impedance Into Electric Power System For Damping Power Oscillations

View page
US Patent:
56420072, Jun 24, 1997
Filed:
Dec 30, 1994
Appl. No.:
8/366646
Inventors:
Laszlo Gyugyi - Penn Hills PA
Colin D. Schauder - Murrysville PA
Assignee:
Westinghouse Electric Corporation - Pittsburgh PA
International Classification:
H02J 324
G05F 170
US Classification:
307102
Abstract:
A series compensator for damping power oscillations in an electric power transmission system includes a switching power converter which injects a voltage into the transmission line having a phase angle relative to transmission line current which is controlled to provide reactive compensation and to inject virtual real impedance into the line. The switching power converter is a dc to ac converter which is capable of injecting virtual real impedance into the transmission line by virtue of the fact that it has a power exchange device connected to its dc terminals. Where the power exchange device is a resistor, the switching power converter is capable of absorbing real power during surges in power on the line. Alternatively, the power exchange device is a storage device such as a battery bank or a super conducting magnet, in which case the switching power converter can provide both virtual positive and negative real impedance.

Three-Phase Dc-To-Ac Power Inverter With Three-Level Poles

View page
US Patent:
58896686, Mar 30, 1999
Filed:
Sep 5, 1997
Appl. No.:
8/924392
Inventors:
Colin David Schauder - Murrysville PA
Scott Lawrence Williams - Voorhees NJ
Assignee:
Electric Power Research Institute, Inc. - Palo Alto CA
International Classification:
H02M 545
H02M 324
H02M 7521
G05F 170
US Classification:
363137
Abstract:
A three-phase dc to-ac power inverter includes a dc power source with a first dc node for positive voltage, a second dc node for negative voltage, and a third dc node for zero voltage. A set of three-level pole circuits are connected to the first dc node, the second dc node, and the third dc node of the dc power source. A control circuit, responsive to an inverter voltage vector reference demand signal with a voltage magnitude reference demand component and a voltage phase reference demand component, generates pole control signals for the three-level pole circuits using logic circuitry which combines phase indexed digital waveform values stored in a pair of lookup tables. The pole control signals force the three-level pole circuits to generate a set of phase-shifted waveforms with zero voltage components. The phase-shifted waveforms are combined by a set of transformers to produce a three-phase output voltage with a harmonic content lower than the harmonic content of the phase-shifted waveforms.

Tacho-Less Vector Control Adaptive System For Motor Drive

View page
US Patent:
48620548, Aug 29, 1989
Filed:
Oct 31, 1988
Appl. No.:
7/265094
Inventors:
Colin D. Schauder - Murrysville PA
Assignee:
Westinghouse Electric Corp. - Pittsburgh PA
International Classification:
H02P 540
US Classification:
318800
Abstract:
Adaptive control is used in an asynchronous motor drive. A reference model based on the model equation of the motor is combined with an adjustable model responsive to the direct and quadrature components of the current and to an estimated speed. An adaptive mechanism counting in a P-I amplifier expands to the direct deviation between the direct and quadrature components of the flux outputed by the two models and generates a feedback signal representing the estimated speed. The adjustable model reacts to such feedback signal so that the estimated speed readily becomes the actual speed of the motor. As a result, a tacho-less AC motor drive is obtained in which under any running conditions the motor immediately takes the required speed.
