  • Publication number: 20160237990
    Abstract: Systems and methods for controlling a renewable energy system based on actual reactive power capability of the renewable energy system are provided. The reactive power output of the renewable energy system can be controlled based at least in part on an initial reactive power limit. The initial reactive power limit can be determined based on rated reactive power for the power generation units in the renewable energy system. When a difference between a reactive power demand and the actual reactive power production of the renewable energy system fall outside a threshold, the initial reactive power limit can be adjusted to a corrected reactive power limit that is closer to the actual reactive power capability of the renewable energy system.

  • Publication number: 20160237996
    Abstract: An improved air compressor includes a cylinder that is fitted with a piston body and defines at its top wall a plurality of exit holes having different diameters and communicating between the cylinder and an air storage container. The exit holes are sealed by plugs and compression springs. The exit holes allow the compressed air produced in the cylinder to enter the air storage container more quickly. When the piston body approaches the top wall of the cylinder, one exit hole, with a smaller diameter, allows the compressed air to enter the air storage container more easily. The exit holes with different diameters allow the piston body to move in the cylinder more smoothly, and thus the efficiency of inflating an object can be increased.

    Abstract: A control system includes a motor, an interface circuit, a motor controller and a detection control circuit. The interface circuit receives and converts a pulse width modulation signal. The fan dissipates heat when the motor is operated in a forward rotation mode and eliminates dust when the motor is operated in a reverse rotation mode. The detection control circuit reads a duty cycle of the converted pulse width modulation signal in real time. When the motor is operated in the forward rotation mode, the detection control circuit drives the motor controller to control the rotation speed of the fan according to the duty cycle. If the duty cycle is lower than or equal to a first threshold value, the detection control circuit drives the motor controller to switch operation mode of the motor from the forward rotation mode to the reverse rotation mode.

  • Publication number: 20160238030
    Abstract: A motor includes a cylindrical housing, a cooling fan, and a rotating shaft. The cylindrical housing defines at least one upstream through hole at its circumferential wall. The cooling fan is mounted at the rotating shaft for generating airflow towards the cylindrical housing for dissipating the heat generated in the motor. The hollow hood is mounted to the cylindrical housing such that a head portion is located above the upstream through hole, thus defining an annular air-guiding channel therebetween, which can receive the airflow generated by the cooling fan and guide the airflow to enter the cylindrical housing via the upstream through holes, so that the heat generated therein can be dissipated effectively. Thus, heat is not easy to accumulate in the motor, and the performance and service life of the motor can be increased.

  • Publication number: 20160238032
    Abstract: A mounting system for a gas turbine engine includes a compressor case portion, an inlet frame, an outlet frame, and a mounting structure. The compressor case portion houses rotatable compressor blades. The inlet frame connects to an inlet end of the compressor case. The outlet frame connects to an outlet end of the compressor case portion at an end opposite the compressor case inlet end. An axially fore mounting structure of the mounting structure connects to the inlet frame. An axially aft mounting structure of the mounting structure connects to the outlet frame. A bridging structure of the mounting structure is offset from the compressor case and connects the fore and aft mounting structures, thereby bridging engine loads across the inlet and outlet frames to reduce load induced distortion of the compressor case portion.
