| Summary |
"Flexible alternating current transmission systems (FACTS) devices are sued for the dynamic control of voltage, impedance and phase angle of high voltage AC lines. The STATCOM is one of the most popular FACTS devices. Integration of storage devices such as batteries, SMES, or ultra-capacitors with a STATCOM can provide active power compensation besides the reactive power compensation to the system. Ultra-capacitors (UCAPS) have a much higher energy storage capacity than regular capacitors. They are also capable of delivering high bursts of power and can rapidly recharge from the transmission system. A STATCOM with an ultra-capacitor can provide extended power availability during voltage sags with momentary interruptions. The dynamic response of STATCOM/UCAP will be shown to be similar to the STATCOM/BESS. Furthermore STATCOM/UCAP will be shown to be effective in damping power oscillations and voltage control will be analyzed during a fault on the system. This thesis will also discuss the integration of ultra-capacitors to diode-clamped multilevel converters"--Abstract, leaf iii. |
