摘要:
A power consumption management system includes power consumption managers (30-1,30-2,30-3) and a power supply manager (10). Each of the power consumption managers (30-1,30-2,30-,3) creates changeable power amount information with respect a planned value of power consumption for each predetermined time range in a preset predetermined period in future, the planned value being related to a load of each piece of equipment in a building (A,B,C) as a monitoring target. The power supply manager (10) is connected to each of the power consumption managers (30-1,30-2,30-3) through a network, decides a power change request amount for each building (A,B,C) based on the created changeable power amount information, and transmits the decided power change request amount to each of the power consumption managers (30-1,30-2,30-3) for the purpose of notification.

According to one embodiment, an energy management system is provided, which has the DSM function of controlling energy loads. The system has a database (10) and a load adjustment range prediction unit (16). The unit (16) predicts a load adjustment range by using the history data stored in the database (10) and outputs the load adjustment range thus predicted.

A plant monitoring apparatus includes: a process measuring unit; a warning determining unit; a warning selecting unit; a display processing unit; a display/ setting unit; a warning criteria setting unit; a warning criteria database; and a warning criteria supplying unit. The warning determining unit determines a plurality of warning data to be issued as warnings from a large amount of process data collected by the process measuring unit on the basis of a predetermined determination criterion. The warning selecting unit compares the plurality of warning data with one or more classification criteria supplied by the warning criteria supplying unit so as to classify the plurality of warning data. Warnings are classified into categories according to the classification and the classified warnings are displayed on the display/setting unit.
摘要:
According to one embodiment, each of the nodes (10-6, 10-7) incorporated in the respective electrical apparatuses (61 to 6M, 71 to 7N) that constitute a local power system (3) establishes a communication path connected to any adjacent node, transmits and receive average supply-and-demand state data to and from the adjacent node through the communication path. Each node (10-6 or 10-7) adjusts (increases or decreases) the power to generate or consume in it, on the basis of the average supply-and-demand state data. Each node (10-6 or 10-7) performs a supply-and-demand control of distributed and coordinated type, in which the average supply-and-demand state value is corrected based on the value by which the power has been adjusted (increased or decreased) and the average supply-and-demand state value thus corrected is supplied to the adjacent node through the connection path.

According to one embodiment, an energy management system includes an energy supply device (10) and an energy demand device (200). The energy management system comprises a first device (11), a second device (201), storage sections (21, 211), calculating sections (20, 210). The first device (11) is applied for the energy supply device (10). The second device (201) is applied for the energy demand device (200). The storage sections (21, 211) are included in the first device (11) and the second device (201), respectively, and store a condition as to comply with an adjustment request of energy supplied from the energy supply device (10) to the energy demand device (200). The calculating sections (20, 210) are included in the first device (11) and the second device (201), respectively, and cooperate to execute negotiation function calculating an energy adjustment amount satisfying the condition.
摘要:
A design support apparatus obtains control parameters of a control system according to characteristic data of the controlled objects dynamics. The apparatus comprises a frequency response curve forming device (8,11) for forming an original frequency response curve of the controlled object according to the dynamic characteristic data of the controlled object; a model selector (4) for selecting one of transfer function models which are low degree transfer functions prepared in advance to approximate original frequency response curves of controlled objects respectively; an approximate curve moving device (17) for moving an approximate curve corresponding to the selected model transfer function toward and away in order to fit the original frequency response curve and fixing a position of the approximate curve; a parameter deciding device(14) for deciding parameters of the selected model transfer function according to the fixed position of the approximate curve; a selector (SWS) for selecting one of control parameters deciding methods; and a control parameters deciding device (5) for deciding the control parameters based on the selected model transfer function and according to the selected control deciding method.
