Systems and methods are provided for the use of systems that recover mechanical power from waste heat energy using multiple working expanders with a common working fluid. The system accepts waste heat energy at different temperatures and utilizes a single closed-loop circuit of organic refrigerant flowing through all expanders in the system where the distribution of heat energy to each of the expanders allocated to permit utilization of up to all available heat energy. In some embodiments, the system maximizes the output of the waste heat energy recovery process. The expanders can be operatively coupled to one or more generators that convert the mechanical energy of the expansion process into electrical energy. |

A life consumption of a component in a machine may be predicted. Load data may be received from a load session of said machine. A plurality of parameter sets may be accessed, each associated with a critical point of said component, which point is considered to have critical life consumption. For each critical point, life consumption may be calculated using a life consumption calculation model receiving said load data and said parameter sets as input. By selecting a plurality of critical points on the component, a more complete view is presented of how the different parts of the component are affected by the load session. |

This invention provides for a production and research facility, which can be known as Ciudad Sinergia, for solving three problems confronting the United States: the need for safe, clean sources of electrical power; the need for adequate supplies of fresh water in arid regions; and the need to dispose of combustible waste in a responsible manner. A synergistic solution to these problems is provided, without the use of nuclear fission, coal or oil. Electrical power is produced by a variety of methods concurrently, including steam turbine-generators, wind turbines, solar cells and collectors, biomass, geothermal and other sources. Burnable trash is provided by cities. Fresh water is produced from desalination plants on the coasts powered by the facility and piped to a man-made lake located at the facility and into the Colorado River. Ciudad Sinergia provides for an emergency source of electrical power and fresh water to California in the event of a major earthquake. |

In order to improve the efficiency of a heat power plant there are proposed combined cycle plants combining a gas turbine plant and a steam turbine plant as a couple. To improve transient response characteristics and ensure steady normal operation of such combined cycle plants, quick response of the gas turbine plant is effectively utilized. The output capacity of gas turbine plants, though it has been increased in recent years, is still far small compared to steam turbine plants. However, the response of gas turbines to a change of load command is far superior to the steam turbines. Accordingly, when the load command changes a gas turbine plant is adapted to off-set the delay in response of steam turbine plant and the shares are subsequently corrected, thereby improving transient response characteristic and ensuring steady normal operation of the whole combined cycle plant.

A low-cost hybrid energy storage system receives energy from one or more external sources, and has an air compressor, low-pressure compressed air energy storage (CAES) system that receives compressed air from the compressor, and a low-temperature thermal energy storage (LTES) system that extracts heat generated by the compression of the air. The LTES system heats an expansion air stream released from the CAES system. The expansion air stream is augmented by air from a turbocharger, and further heated by the exhaust stream of a power turbine. At least a portion of the augmented air stream is further heated in a high-temperature thermal energy storage system that receives energy from the one or more external source. The augmented stream is directed to the turbocharger, and then through the power turbine to generate output energy. |
