摘要:
An abnormal torque evaluation apparatus is applied to an electrically driven vehicle configured to drive left and right driving wheels independently with respective electric motors and also configured to independently drive the left and right driving wheels by means of the electric motors driven responsively to respective torque commands. Also provided are a yaw jerk detection means for detecting a yaw jerk and an abnormal torque evaluator for evaluating, based on the yaw jerk, the presence or absence of the occurrence of abnormal motor torque at the electric motors.

A power demand/supply management server (10) obtains information defining restraint contents to a comfort and an electricity bill from a consumer power operating device (2). An individual-consumer control optimizing unit of the power demand/supply management server (10) calculates control contents to an electrical equipment having a minimum cost evaluation value based on a simulation result of cost evaluation values which are barometers for evaluating a comfort and an electricity bill excessiveness, and transmits the calculated control contents to the consumer power operating device (2). Also, a whole-consumer optimizing unit of the power demand/supply management server (10) calculates the most appropriate electricity unit meter-charge that ensures a necessary demand suppression plan level throughout the whole power system based on an electricity daily load curve for each consumer.

Energy demand in an entire community including multiple demanders is properly predicted and energy consumption thereof is properly controlled. Every day, some demanders are selected from the community and a request to adjust energy consumption for the following day is sent to the selected demanders. To decide a content of the request, energy demand for the following day is predicted. In this case, demanders which did not receive a request on past days are specified, and demand in the community for the following day is predicted based on the actual energy consumption by those demanders on the past days.

A power demand regulating apparatus is provided which can efficiently achieve the purpose of peak shift in a power system and which can reduce the total incentive which an operator of a demand regulation server distributes to consumers having cooperated with a request for regulating an amount of energy to be used. A demand regulation server (0101) is provided with a cooperation level determining function (0111) of calculating a cooperation level which is obtained by quantifying the height of a cooperation sense of a consumer with a request for regulating an amount of energy to be used. The operator of the demand regulation server observes consumers or consumer appliances responding to the request for regulating an amount of energy to be used on the basis of the magnitude of the cooperation level and transmits the request to only the consumers or the consumer appliances.

It is an object of the present invention to provide a load leveling system of a power system capable of attaining load leveling in a distribution substation unit and a method thereof. Disclosed is a load leveling system of a power system with a controller having a major customer and lower transforming apparatus, and with a customer connected to the lower transforming apparatus via a low-voltage line. The system also has a communication unit between the customer and its own system, and control use time zones of devices within the customer; an electric demand prediction unit, and a first load leveling processing unit. By employing such an arranged system, it becomes possible to provide a load leveling system of a power system capable of realizing load leveling of both a distribution substation unit and a pole transformer unit.

A solar power generation system comprising: plural customers each having a solar panel, a power convertor for converting DC output from the solar panel into AC output, an output controller for suppressing the power convertor output which becomes higher than a predetermined value, a measuring unit for measuring the amount of sold power, the amount of purchased power and the amount of generation-suppressed power; and an watt-hour meter measurement data adjusting unit linked with the plural customers via communication lines. The watt-hour meter measurement data adjusting unit calculates provisional generation-suppressed power amounts that make the burdens of the customers even, and calculates the power amounts to be sold by the customers on the basis of the provisional generation-suppressed power amounts. Thus, the generation-suppressed power of the solar power generation system can stabilize the power system and the chances for selling power can be fairly allocated to customers having solar panels.

In mode transfer control apparatus and method for a hybrid vehicle, in a state in which the vehicle is in at least one of a start state and a travel state and in one steady-state mode of a continuously variable transmission gear ratio mode and a fixed transmission gear ratio mode, a mode transfer to the other steady-state mode of the continuously variable transmission gear ratio mode and the fixed transmission gear ratio mode is inhibited in a case where a driving point of the vehicle determined according to a detection value of a vehicle speed and a calculation value of a target driving force is present within an overlap area on a steady-state mode area map in which both of a continuously variable transmission gear ratio mode and a fixed transmission gear ratio mode are selectable.
摘要:
A disc includes a disc substrate having a major surface operating as a signal recording portion and having a substantially circular center opening in the major surface, and a hub mounted on the disc substrate for closing the center opening in the disc substrate. The hub includes an inner rim portion having a spindle opening at its center and an outer rim portion connected to an outer side of the inner rim portion for extending from the inner rim portion via a step difference towards the side of insertion in the spindle opening. When the hub is set on a disc table, the outer rim portion protruded on the side from which the spindle is inserted into the spindle opening with a step difference approaches a magnet provided on the disc table to increase the force of suction by the magnet so that the magnetic disc is chucked with respect to the disc table solely by the force of the magnet.

A signal recording medium capable of being strongly secured to a rotation part such as a disc table even during high-speed rotation includes a floppy disc with a hub at its center portion and a disc substrate having a disc-shaped main portion with a circular opening operating as a mounting portion for the hub. The disc substrate has also a signal recording surface on the disc-shaped main portion. The hub includes an abutment surface abutted against the disc table and rotated in unison with the floppy disc and a facing suction surface spaced apart from a suction magnet mounted on a rim portion of the disc table when the abutment surface is abutted against a hub setting surface of the disc table.

Energy demand in an entire community including multiple demanders is properly predicted and energy consumption thereof is properly controlled. Every day, some demanders are selected from the community and a request to adjust energy consumption for the following day is sent to the selected demanders. To decide a content of the request, energy demand for the following day is predicted. In this case, demanders which did not receive a request on past days are specified, and demand in the community for the following day is predicted based on the actual energy consumption by those demanders on the past days.
