摘要： A system for monitoring maintenance information in a hydroelectric power generation facility comprises sensors coupled to a controller. The sensors detect actual levels of operating parameters for a desired operating period at an operating condition. The detected parameters include a stressor capable of affecting a life span, or mean time between failures, of the turbine or one of its components. The controller determines the amount of the life span used up. A method for monitoring maintenance information in a power generation facility includes the steps of monitoring levels of operating parameters including a stressor for a desired operating period at an operating condition. The stressor affects the life span of the turbine or one of its components, and the amount of the life span used up over the operating period is calculated. A method for monitoring losses in a hydroelectric power generation facility operating to satisfy environmental constraints involves storing predetermined reference signals representative of desired turbine efficiencies over a range of operating levels in a memory circuit. Current levels of operating parameters are sensed while the facility is operating to satisfy the environmental constraints. A sensed parameter signal representative of a current turbine efficiency is generated from the sensed levels of operating parameters. The generated parameter signal is compared to the predetermined reference signals to determine an environmental efficiency loss signal.

摘要： Disclosed is a method for aligning a position sensor in a vehicle with steerable wheels comprising obtaining an absolute position value responsive to a position signal from a handwheel position sensor, obtaining a relative position value responsive to an encoder signal count from a position encoder, and obtaining an index position value responsive to an index position signal. The method further includes receiving an alignment enable signal and determining a correction factor responsive to the relative position value and the index position value. The method for aligning a position sensor is responsive to at least one of the absolute position value, the relative position value, and the index position value under conditions determined from the status of the alignment enable signal. Also disclosed is a method for aligning a steerable wheel in a vehicle with electric power steering comprising obtaining an alignment correction corresponding to a computed correction of wheel position relative to the vehicle from an alignment apparatus, receiving an alignment enable signal, where the method of aligning is responsive to the alignment correction under conditions determined from the status of the alignment enable signal.

摘要： An intelligent network demand control system provides a system and method for controlling demand in an energy delivery system. The intelligent network demand control system employs a transceiver network with a plurality transceivers coupled to meters and appliances residing at a plurality of customer premises. Control room operators instruct a customer premises (CP) energy management controller to implement a reduction in system demand. A demand reduction control signal is relayed out to a predefined group of transceivers to shut off their respective controlled appliances. The predefined transceivers, identified by their identification codes, are specified in the demand reduction control signal. When the transceivers shut off the appliances in response to a broadcasted demand reduction control signal, the actual demand reduction is metered and relayed back to the CP energy management controller. The total demand reduction is aggregated into a single number and then communicated to the operators.

摘要： In the electric power system protective control system, a plurality of protective control apparatuses each having a protective control function to an electric power system are distributed and connected through a communication network to each other so that data communication is permitted among the respective protective control apparatuses. Each of the protective control apparatuses is carried out a process of executing a control operation related to the protective control function of the own apparatus according to a program module. The program module migrates through the communication network to the own apparatus along a predetermined route of migration. Each of the protective control apparatuses executes a process of migrating the program module from the own apparatus to another protective control apparatus. The another protective control apparatus is determined to a next destination of migration according to the route of migration. In a case where the program module is not migrated by the migration process to the next destination protective control apparatus, each of the protective control apparatuses executes a process of changing a next destination of migration of the program module to a predetermined protective control apparatus except for the next destination protective control apparatus, making it possible to prevent the program module from stopping.

摘要： A method, system and computer program product enhance the commercial value of electrical power produced from a wind turbine production facility. Features include the use of a premier power conversion device that provides an alternative source of power for supplementing an output power of the wind turbine generation facility when lull periods for wind speed appear. The invention includes a communications infrastructure and coordination mechanism for establishing a relationship with another power production facility such that when excess electrical power is produced by the wind turbine facility, the excess may be provided to the power grid while the other energy production facility cuts back on its output production by a corresponding amount. A tracking mechanism keeps track of the amount of potential energy that was not expended at the other facility and places this amount in a virtual energy storage account, for the benefit of the wind turbine facility. When, the wind turbine power production facility experiences a shortfall in its power production output it may make a request to the other source of electric power, and request that an increase its power output on behalf of the wind turbine facility. This substitution of one power production facility for another is referred to herein as a virtual energy storage mechanism. Furthermore, another feature of the present invention is the use of a renewal power exchange mechanism that creates a market for trading renewable units of power, which have been converted into “premier power” and/or “guaranteed” by secondary sources of power source to provide a reliable source of power to the power grid as required by contract.
