摘要： The invention is a system and method for smoothly starting and controlling an ORC power plant. The system comprises a cascaded closed loop control that accounts for the lack of relationship between pump speed and pressure at startup so as to control pump speed and pressure, and that smoothly transitions into a steady state regime as a stable operating condition of the system is attained. The cascaded loop receives signals corresponding to a superheat setpoint, a pressure at an evaporator exit, and a temperature at an evaporator exit, and controls the pump speed and pressure upon startup to provide smooth operation. The system and method can further comprise a feed-forward control loop to deal with conditions at start-up and when external disturbances are applied to the ORC power plant.
摘要翻译：本发明是一种用于顺利启动和控制ORC发电厂的系统和方法。该系统包括级联闭环控制，其考虑了启动时泵速度和压力之间缺乏关系，以便控制泵的速度和压力，并且在达到系统的稳定运行状态时平滑地转变为稳态状态。级联环路接收对应于过热设定点，蒸发器出口处的压力和蒸发器出口处的温度的信号，并且在启动时控制泵速度和压力以提供平稳的操作。该系统和方法还可以包括前馈控制回路以处理启动时的状况，以及当外部干扰被施加到ORC发电厂时。

摘要： The invention is a system and method for synchronizing an induction machine to an electrical grid (170). The embodiment described is an ORC power plant having a motor-generator (150) in mechanical communication with a turbine (140). The motor-generator (150) is operated with open windings (e.g., freewheeling) by driving the turbine with a variable speed pump (120) . The rotational speed of the motor-generator (150) is sensed. When the motor-generator (150) is operating at a rotational speed near the steady state rotational speed that corresponds to operation of the ORC power plant, the contacts between the motor-generator windings and the grid (170) are closed, and the motor is synchronized with the grid (170).
