Abstract:
Various systems and methods are provided for autotensioning conductors of transmission lines. In one embodiment, among others, an autotensioner system includes tensioning assemblies coupled between a structure and corresponding conductors and a tension controller that controls a tensioning assembly to adjust a tension of the corresponding conductor to within a predefined tolerance of a corresponding tension setpoint. In another embodiment, a method includes receiving a current conductor tension for each of multiple conductors and adjusting the conductor tension of one of the conductors by remotely controlling a corresponding tensioning assembly. The adjustment may be based at least in part upon the current conductor tensions and a tension setpoint.
Abstract:
A coal feed system to feed pulverized low rank coals containing up to 25 wt % moisture to gasifiers operating up to 1000 psig pressure is described. The system includes gas distributor and collector gas permeable pipes imbedded in the lock vessel. Different methods of operation of the feed system are disclosed to minimize feed problems associated with bridging and packing of the pulverized coal. The method of maintaining the feed system and feeder device exit pressures using gas addition or extraction with the pressure control device is also described.
Abstract:
Disclosed are various embodiments for elevating a user account by granting administrator permissions to workstations of network users. One embodiment of such a method comprises receiving authorization to provide a user temporary membership to an administrators group for a defined period of time; sending instructions to a workstation of the user to register as a member to the administrators group of the workstation; and in response to the membership having expired, sending instructions to remove the user as a member of the administrators group on the workstation.

Abstract:
Various methods and systems are provided for evaluation of events such as the startup of power generation units. In one embodiment, a method includes obtaining operational data associated with a power generation unit, the operational data corresponding to a predefined period of time; determining start and end times for a startup phase associated with the power generation unit based upon a set of predefined startup conditions corresponding to the startup phase; and generating a network page including the start and times. In another embodiment, a system includes a unit evaluation system executable in a computing device that includes logic that obtains operational data associated with a power generation unit, the operational data corresponding to a predefined period of time and logic that determines start and end times for an event phase associated with the power generation unit based upon a set of predefined conditions corresponding to the event phase.
Abstract:
Disclosed are various embodiments for communicating with an integrated distribution management system (IDMS). An IDMS often employs a communications protocol that is incompatible with a service oriented architecture. Accordingly, embodiments of the disclosure can allow utility computing systems in a service oriented architecture or in a messaging based environment to communicate with an IDMS.
Abstract:
Disclosed are various embodiments of locking systems that include a barrel lock. The barrel lock is configured to damage, deface, and/or capture a key that is inserted into the barrel lock. Additionally, some embodiments include a locking mechanism adapter that can allow the locking mechanism to be operated by a key if the user has knowledge about the properties of the barrel lock.
Abstract:
Devices, systems, and methods improve particulate filtration. A particulate filtration system is implemented within a fossil fuel power plant combustion system. A gas containing particulates flows through the filtration system. The filtration system comprises a collection hopper for collecting the particulates. Within the collection hopper, a particulate trap, upper baffles, and lower baffles are provided to retain collected particulates in the hopper and, thereby, improve the filtration of particulates from the gas flow. The particulate trap can include two sets of variously oriented, interconnecting retaining members crossing the interior of the collection hopper.
Abstract:
Disclosed are various embodiments for a workstation management application. An identification of a user is obtained in a user interface. A listing of workstations that the user has accessed is rendered in the user interface. A selection of one of the workstations is obtained in the user interface. A listing of management tasks configured for the workstation is rendered in the user interface. One of a plurality of management tools is launched to perform a selected one of the management tasks for the workstation.
Abstract:
A method, system, and computer readable storage medium for auditing the installation of smart meters via a computer system. The method includes receiving a plurality of installation data for each smart meter installed; loading the plurality of installation data into an auditing utility operating on the computer system based on auditing criteria; performing an audit for each smart meter installed via the auditing utility; submitting the audit for each smart meter installed for recording in an audits database; verifying the audit for each smart meter installed; and generating and analyzing audit reports stored in the audits database.
