Power generation control system, power generation control method, program, and medium

Abstract

It has been difficult to reduce a waste of energy in a fuel cell power generating process when, for example, a temporary rise or drop of a power load occurs. A fuel cell power generation system includes: load detection means of detecting power requested by a load; and output control means of accumulating a time at which a detected power requested by the load is equal to or larger than a predetermined value when a fuel cell body does not generate power to be supplied to the load, and allowing the fuel cell body to start generating power to be supplied to the load according to a predetermined rule based on an accumulation result.

1 - 35 . (canceled)  
   
   
       36 . A power generation control system for use with a predetermined power generator, comprising: 
 a power detector detecting power in at least a first predetermined period requested by a load; and    a power generation controller controlling the predetermined power generator generating all or a part of power to be supplied to the load, by using a command value generated during every second predetermined period based on an average value of the detected power in the first predetermined period, except for a case where the second predetermined period coincides with the first predetermined period,    wherein the command value generated during every second predetermined period is generated based on the average value in the first predetermined period having an end time equal to a starting time of the second predetermined period, and    said predetermined power generator is a fuel cell power generator which comprises a hydrogen supplier having a reformer, an air supplier, and a fuel cell generating power by using hydrogen supplied by said hydrogen supplier and oxygen supplied by said air supplier.    
   
   
       37 . The power generation control system according to  claim 36 , wherein excess or shortfall of the generated power relative to the requested power is adjusted by using system power and/or a battery.  
   
   
       38 . The power generation control system according to  claim 37 , wherein: 
 the excess or shortfall of the generated power is adjusted by using system power and the battery; and    the battery is used by priority over the system power.    
   
   
       39 . The power generation control system according to  claim 37 , wherein control is performed by amending the command value corresponding to a difference between an amount of accumulation of the battery and a predetermined target amount of accumulation of the battery.  
   
   
       40 . A fuel cell power generator, comprising: 
 a hydrogen supplier having a reformer;    an air supplier;    a fuel cell generating power by using hydrogen supplied by said hydrogen supplier and oxygen supplied by said air supplier and the power generation control system according to  claim 36 .    
   
   
       41 . A power generation control method, comprising the steps of: 
 detecting power in at least a first predetermined period requested by a load; and    controlling a predetermined power generator generating all or a part of power to be supplied to the load, by using a command value generated during every second predetermined period based on an average value of the detected power in the first predetermined period, except for a case where the second predetermined period coincides with the first predetermined period,    wherein the command value generated during every second predetermined period is generated based on the average value in the first predetermined period having an end time equal to a starting time of the second predetermined period, and    said predetermined power generator is a fuel cell power generator which comprises a hydrogen supplier having a reformer, an air supplier, and a fuel cell generating power by using hydrogen supplied by said hydrogen supplier and oxygen supplied by said air supplier.    
   
   
       42 . A computer program product for directing a computer to function as the power generation controller of the power generation control system according to  claim 36 , by: 
 controlling a predetermined power generator generating all or a part of power to be supplied to the load, by using a command value generated during every second predetermined period based on an average value of the detected power in the first predetermined period, except for the case where the second predetermined period coincides with the first predetermined period.    
   
   
       43 . A computer-processible medium storing a computer program product according to  claim 42.
