摘要： PURPOSE:To estimate the index values of coordinate points over a wide range of space by estimating the index values of coordinate points having unknown index values on the basis of the variation of a plurality of coordinates having known index values. CONSTITUTION:An index-estimating apparatus 1 is composed of an estimation and processing part 2 and data bases 3, 4. Data on stability indexes are housed in said data base 3 and limited data indicating characteristics relative to the variation of index values of stability space are housed in said data base 4. Three points of facts A, B, C are selected from said data base 3 and the combination of the facts A and C and that of the facts B and C are used to prepare a hypotensis on stability, capability of indexing and its reliability, to check any inconsistency with the constraint by a checking device for inconsistency of hypotensis and to correct said hypotensis and eliminate said inconsistency. Thus, it is possible to check the reliability of said apparatus on, e.g. whether the electric system is safe or not.

摘要： PURPOSE:To lighten the burden of voltage control operation onto a central computer and to deal with the voltage control operation flexibly by determining a reactive power injection amount based on a reference amount provided from the central computer and requesting assistance to devices at other ends if the injection amount can not be supplemented at this end. CONSTITUTION:Upon voltage drop at node 5, rules 1 and 2 are started alternately in a compensator 10d and reactive output power increases. When the reactive output power saturates, rule 3 is started in place of rule 2. Other devices 10a, 10b, 10c, which are requested assistance from the compensator 10d, actuate rule 4 simultaneously and notify their contribution to the compensator 10d, which then selects a device for requesting assistance according to rule 5. At that time, rule 6 is actuated in the compensator 10a and the terminal voltage of the compensator 10d increases within an allowable range.

摘要： PURPOSE:To decentralize load from a central computer and to realize an efficient control by distributing power generation system controllers to respective power stations in order to regulate the load within a predetermined range and then regulating the power flow distribution through self-judgment based on neighboring power flow information and communication with other power generation system controllers. CONSTITUTION:A power supply control system 13 comprises a central computer 2, a communication transmitter 3 and power generation system controllers 12a, 12b.... Power control operation is distributed between respective power generation controllers 12a, 12b. Inference sections 8a, 8b,... communicate mutually through communication control sections 7a, 7b,... and the communication transmitter 3 according to procedures stored in data base sections 9a, 9b,... thus effecting coordination function with no assist of the central computer 2. Consequently, the load does not concentrate to the central computer and each distributed computer regulates the power flow distribution based on self- judgment, resulting in the improvement of controllability and highly reliable operation.

摘要： PURPOSE:To attain the automation and rapid operation of forecasting work and to improve the accuracy of forecasts by converting various experiences and knowledge into knowledge bases and using the knowledge base for inference to execute statistic processing. CONSTITUTION:Data necessary for a forecast are inputted from an input part 15. An inference mechanism 13 selectively controls knowledge necessary for the control knowledge 141 of a knowledge base part 14. In the initial processing, the input data are judged, weekday reference forecasting knowledge 142 or specific day reference forecasting knowledge 143 is selected in accordance with a weekday or a specific day on the forecasting day and selects a forecasting system based upon the selected knowledge. Then, forecasting value calculating processing is executed based upon the selected forecasting system. The forecasting value calculating processing calculates the post data stored in an actual data part 12 based upon the selected forecasting value calculating processing. When necessary, the forecasted value is corrected by correction knowledge held by forecasted value correcting knowledge 144. Finally, the forecasted value is evaluated by evaluation knowledge 145. The obtained evaluation value of the forecasted value (f) is outputted to an outputted part 16 and displayed.

摘要： PURPOSE:To easily reduce and extend passing communication lines by assigning numbers 0 to n-1 to each computers and by connecting computers having the relation of i=2j (modulo n), i'=2j+1 (modulo n), j=0, 1, ..., n-1, to computers by a bidirectional communication line at the time of allocating the numbers to the respective computers. CONSTITUTION:For instance, when information is transferred to the computers of the number 0 to 8, it is transferred to the computer of the number 8 via the computers of the numbers 1, 2, 4 and the communication line therebetween, a hierarchy type system can be constituted and the information can be trans ferred only by passing the four communication lines to the maximum. When the communication line connecting the computers of the numbers 5 and 10 is failed, the information is transferred to the computer A of the number 10 from the computer of the number 5 via the computers the numbers of 2, 1, 0 and the communication line therebetween, thereafter, via the computers of the numbers 15, 14, 13 and the communication line therebetween and the informa tion can be transferred via the nine communication lines to the maximum.
