The present invention relates to a control device for a fuel cell power generation system that aims to improve controllability of pressure in a fuel reforming system and improve load followability.

In order to maintain the representative pressure of the fuel reforming system stably with respect to the standard set flow rate according to the load and battery current, a correction value is given based on the deviation between the main pressure set value and the detected value.

In the figure, reference numeral 1 denotes a raw material gas reference setting flow rate calculation section, 2 and 3 regulators, and 4 a raw gas flow rate control valve. In this conventional example, the raw material gas standard setting flow rate calculating section 1 inputs the battery flow rate a and generates the standard setting flow rate S.
Furthermore, in order to maintain the pressure in the representative part of the fuel reforming system appropriately, the regulator 2 gives a correction value e based on the deviation between the set value C and the detected value d, and the sum of b and e is used as the set flow rate f. The configuration is as follows. Furthermore, in this configuration, in order to make the actual flow rate follow the set flow rate f, the regulator 3 gives a second opening command to the flow rate control valve 4c from the set flow rate f and the detection @g.

料が供給できなくなる等の問題があった。(Problems to be Solved by the Invention) In the fuel cell power generation system having the above configuration, the transmission of gas flow in the fuel reforming system is difficult. Due to the delay, there were problems such as the pressure in the fuel reforming system dropping when the load increased, making it impossible to properly supply fuel to the fuel cell.

る。In the fuel reforming system, reaction devices such as a reformer 5, a high temperature shifter 6, and a low temperature shifter 7 are arranged in series, and since they have a reaction catalyst layer, they have a relatively large resistance to flow. Therefore, in this system, the gas flow propagation t
r! ! The delay is large, and even if the gas flow rate is increased by the raw material gas flow rate control valve 4, it takes a relatively long time for the increase to propagate to the fuel reforming system separator 8. Now, considering the case where the load does not increase, the amount of fuel required for the fuel cell increases, so the cell anode fuel flow control valve 9 opens and operates to increase the fuel flow rate. However, in such a configuration, as the pressure in the separator 8 decreases due to the propagation delay, the primary pressure in the control valve 9 decreases, making it impossible to supply sufficient fuel to the fuel cell. Note that the representative pressure of the fuel reforming system in the conventional example includes, for example, the internal or outlet pressure of the separator 8 in FIG. 4.

消され、改質系の圧力上昇を抑える作用がある。(Function) Therefore, when the load increases in the fuel cell power generation system and the cell current increases, the supply amount of 1liX feed gas is increased in advance, thereby reducing the gas propagation delay in the fuel reforming system. The effect is to counteract this and prevent the pressure drop in the reforming system. Conversely, when the load decreases, the raw material gas is narrowed down in advance, which cancels out the gas propagation delay and has the effect of suppressing the pressure rise in the reforming system.

後の圧力に良好に追従することになる。In response to such an increase in load, in the conventional configuration shown in Figure 3, the FX feed gas exhibits an increase day response as shown in F2 as the load increases, and due to the gas propagation delay in the fuel reforming system mentioned above, the reforming system The representative pressure decreases transiently like F2. On the other hand, according to the embodiment of the present invention, the raw material gas acts to increase progressively as shown by Fl in FIG. It follows the pressure well.
