Publication number: 20140148966Abstract: A general decentralized voltage control scheme is proposed to coordinate the operation of DG, Voltage regulator and Capacitor banks. The present invention is based on placing a Remote Terminal Unit (RTUs) at each distribution generation (DG) and each at line capacitor. These RTUs being coordinated together through communication protocols form a multi-agent system. Novel decentralized system is proposed to estimate the voltage profile change as a result of injecting reactive power at the capacitor bus. Simulation results are presented to show the validity and the effectiveness of the present invention.Type: ApplicationFiled: November 29, 2012Publication date: May 29, 2014Inventors: Magdy Salama, Ramadan El-Shatshat, Mohamed El-Khatib, Mohamed Ahmed

Patent number: 7477529Abstract: A high-voltage power supply (10) includes: a power scaling section (130) that receives an input voltage signal and converts the input voltage signal to a controllable DC voltage; a push-pull converter (140) for converting the controllable DC voltage to a high-frequency wave; and a voltage multiplier (200) receiving the high-frequency wave generated by the push-pull converter (140) and performing successive voltage doubling operations to generate a high-voltage DC output. In one implementation, the voltage multiplier (200) receives a square wave having a frequency of approximately 100 kHz and outputs an adjustable DC voltage of approximately 0-to-30 kV. In one implementation, the high-voltage power supply (10) includes an insulation system (250) for the voltage multiplier module (200), such an insulation system being formed of n insulating layers and m conducting strips positioned between successive insulating layers.Type: GrantFiled: July 31, 2003Date of Patent: January 13, 2009Assignee: Honeywell International inc.Inventors: Magdy Salama, Mehrdad Kazerani, Chun Ho Lam
