    摘要： A closure for pipeline pig sender or receiver includes a primary closure body and a secondary closure body. The primary closure body has an outer face, an inner face and a port extending therethrough from the outer face to the inner face. The primary closure body is secured to the pipeline pig sender or receiver sealing a closure end when the primary closure body is in the closed position. The secondary closure body closes the port on the primary closure body. The secondary closure body is movable between a closed position and an open position to enable an operator to insert a tool through the port into the diversionary passage to manipulate the pipeline pig and release trapped pressure prior to opening the closure. The secondary closure body is secured to the primary closure body sealing the port when the secondary closure body is in the closed position.

    摘要： A fault detection system is provided, and includes a generator, a power converter, a breaker, a current monitoring device, and a control module. The power converter is selectively connected to the generator and is selectively activated to produce a test voltage. The breaker is located between the generator and the power converter for selectively connecting the generator to the power converter. The breaker includes an open position and a closed position. The current monitoring device is located between the generator and the power converter. The current monitoring device measures a line current between the generator and the power converter. The control module is in communication with the current monitoring device and the power converter. The control module has a memory with a threshold current value.

    摘要： Systems, methods, and apparatus for supplying AC power to an AC power grid from a DC power source, such as a photovoltaic (PV) array are disclosed. The systems and methods can include a converter coupled to the DC power source that provides DC power to a DC bus at a DC bus voltage. The systems and methods can further include an inverter coupled to the DC bus for converting the DC power of the DC bus to an output AC power. The systems and methods can further include a control system configured to regulate the DC bus voltage of the DC bus to operate at a variable DC bus voltage setpoint. The control system can adjust the DC bus voltage setpoint based at least in part on the DC bus voltage and the output AC current of the inverter.

    摘要： A method for controlling operation of a wind turbine included within a power generation and delivery system is described. The method includes measuring at least one operating condition of the power generation and delivery system. The method also includes transmitting, to a power limiter system, an operating condition feedback signal that corresponds to the operating condition. The method also includes analyzing the operating condition feedback signal to identify an occurrence of a grid contingency event and generating a real current command signal corresponding to an occurrence of a grid contingency event. The method also includes transmitting the real current command signal to a controller and applying the real current command signal to power converter performance to facilitate reducing pole-slipping. The method also includes storing, in a memory, at least one variable corresponding to the operating condition upon the occurrence of a grid contingency event.

    摘要： By controlling one or more properties of a gasoline-oxygenate blend, a gasoline-oxygenate blend may be blended to contain at least one alcohol that exhibits acceptable properties and characteristics. This blend and the preferred method of preparing this blend includes an alcohol, most preferably ethanol, to reduce or eliminate the introduction of MTBE while offering acceptable properties such as volatility and temperature while effectively reducing pollutant emissions.
