  • Publication number: 20120245748
    Abstract: Control system and method for controlling an integrated gasification combined cycle (IGCC) plant are provided. The system may include a controller coupled to a dynamic model of the plant to process a prediction of plant performance and determine a control strategy for the IGCC plant over a time horizon subject to plant constraints. The control strategy may include control functionality to meet a tracking objective and control functionality to meet an optimization objective. The control strategy may be configured to prioritize the tracking objective over the optimization objective based on a coordinate transformation, such as an orthogonal or quasi-orthogonal projection. A plurality of plant control knobs may be set in accordance with the control strategy to generate a sequence of coordinated multivariable control inputs to meet the tracking objective and the optimization objective subject to the prioritization resulting from the coordinate transformation.

  • Publication number: 20120245747
    Abstract: System and method to estimate variables in an integrated gasification combined cycle (IGCC) plant are provided. The system includes a sensor suite to measure respective plant input and output variables. An extended Kalman filter (EKF) receives sensed plant input variables and includes a dynamic model to generate a plurality of plant state estimates and a covariance matrix for the state estimates. A preemptive-constraining processor is configured to preemptively constrain the state estimates and covariance matrix to be free of constraint violations. A measurement-correction processor may be configured to correct constrained state estimates and a constrained covariance matrix based on processing of sensed plant output variables. The measurement-correction processor is coupled to update the dynamic model with corrected state estimates and a corrected covariance matrix. The updated dynamic model may be configured to estimate values for at least one plant variable not originally sensed by the sensor suite.

  • Patent number: 8245086
    Abstract: Techniques are disclosed for conveying which hardware components of a logically partitioned computer system are assigned to a selected logical partition of the computer system. Partition information for the computer system is received. Further, a request is received from a user to view which hardware components of the computer system are assigned to a selected logical partition of the computer system. Based on the received partition information, one or more hardware components are determined that are assigned to the selected logical partition. Based on the determined hardware components, a virtual model of the computer system is generated that visually distinguishes hardware components assigned to the selected logical partition from hardware components not assigned to the selected logical partition. The virtual model is output responsive to the request.

  • Publication number: 20120159510
    Abstract: Techniques are described for managing states of an object using a finite-state machine. The states may be used to indicate whether an object has been added, removed, requested or updated. Embodiments of the invention generally include dividing a process into at least two threads where a first thread changes the state of the object while the second thread performs the processing of the data found in the object. While the second thread is processing the data, the first thread may receive additional updates and change the states of the objects to inform the second thread that it should process the additional updates when the second thread becomes idle.

  • Patent number: 8140717
    Abstract: A low-level logical partitioning function associates partitions, partitionable entities, and location codes. Partitionable entities are hardware components, not necessarily individually replaceable. The location code reflects the physical topology of the system packaging. It is preferably a string of concatenated elements, each element representing a device in a hierarchical level of devices which may contain other devices. A respective location code is likewise associated with each of multiple physical indicators. The location code of partitionable entities allocated to a partition is compared with the indicator's location code to determine whether a process executing within a partition can access the indicator. Preferably, each partition has a virtual indicator corresponding to a physical indicator, the state of the physical indicator being derived as a function of the states of multiple virtual indicators for multiple partitions.

  • Publication number: 20110219371
    Abstract: A management system for managing computer resources assigned by a hypervisor to one or more logical partitions and/or one or more appliance partitions in a multi-user computer system receives login information from a new user logging into the computer system through a service interface (e.g. a hardware management console) or a non-service interface, builds a conflict list, and sends the conflict list for presentation to the new user. The new user is notified of any users that are logged into any part of the computer system that could conflict with the new user's actions. Such users may be logged into the computer system through service and/or non-service interfaces. In one embodiment, the new user can choose to continue logging in irrespective of any conflicts shown. After choosing to continue, the new user is preferably requested to input an end-time. This end-time may be displayed, in turn, to all subsequent users that log into any part of the computer system that could cause conflict.

  • Publication number: 20090064581
    Abstract: A plasma-assisted waste gasification system and process for converting waste stream reaction residues into a clean synthesis gas (syngas) is disclosed. The feedstock is fed into a reactor roughly one-third from the bottom through the use of a feed mechanism. The reactor has three zones; a bottom zone where melting occurs, a middle zone where gasification takes place, and a top zone with integrated plasma torches to control the temperature and polish the syngas. The residence times in the three zones are selected to optimize the syngas composition and melted products. The syngas leaves the reactor and is partially quenched with relatively cooler synthesis gas. The partially quenched syngas is further cooled to recover heat for steam generation and/or preheating the waste stream to the reactor. The cold syngas is then processed to remove pollutants. The clean synthesis gas is combusted in power generation equipment to generate electricity, or converted to other fuels by chemical processes.
