摘要： This application relates to a cell (1200) or sub-module for a voltage source converter (1201). The cell includes an energy storage apparatus (101; 101a, 101b) and a plurality of dual-switch semiconductor packages (201), each having first and second semiconductor switches (202, 203) connected in series. The cell is operable in an active state in which an energy storage apparatus (101; 101a, 101b) is electrically connected in series between cell terminals (102a, 102b) and a bypass state in the cell terminals (102a, 102b) are electrically connected via a path that bypasses the first energy storage apparatus. The plurality of dual-switch semiconductor switch packages are configured to provide a first set of semiconductor switches (301;401) connected between nodes of the cell that are electrically connected in the first active state and electrically disconnected in the first bypass state; and a second set of semiconductor switches (302a, 302b; 402a, 402b) is connected between nodes of the cell that are electrically disconnected in the first active state and electrically connected in the bypass state. The second set of switches comprises a greater number of switches in parallel than the first set of switches.

摘要： The present application provides a method of evaluating valve creep damage in a turbine by a data acquisition system. The method may include the steps of receiving a number of operating parameters from a number of sensors including steam temperatures and steam pressures about the valve over time, generating a design material model for the valve, determining an indicator for consumed creep lifetime based on the steam temperature and steam pressures about the valve over time as compared to the design material model, and altering one or more of the operating parameters and/or initiating repair procedures based upon the consumed creep lifetime indicator.

摘要： An apparatus may have a first reflector and a second reflector positioned on either side of a sample volume for a gas sample. The configuration of the first reflector may be variable between at least first and second configurations, wherein each of the first and second configurations is arranged such that a beam of optical radiation from an optical beam origin is directed to a detector location via the sample volume. In the second configuration the beam of optical radiation is reflected at least once from each of the first and second reflectors and the path length of the beam of optical radiation through the sample volume is greater than in the first configuration.
