が定格電圧Ｅに正しく保持される。The present invention operates as follows. The output performance and the power generation efficiency of the engine 1 and the generator 2 may decrease due to the difference in solids during mass production or the bad influence in a high temperature atmosphere, and the output voltage of the generator 2 may decrease. In this case, the detected voltage V detected by the voltage detector 10 becomes lower than the rated voltage E, but the reference rotational speed calculation means 7 first follows the engine rotational speed indexing curve D shown in FIG. (A)
As shown in the flowchart of FIG. 2, from the values C1 to C10 of the load detection current C detected by the current detector 6 in step S1,
The memory address is set in step S2, and step S
At 3, the values N1 to N10 of the reference target rotation speed N recorded in the memory address are calculated and set. Next, at step 31, the routine proceeds to the correction rotational speed F setting subroutine by the correction value calculating means 11 shown in FIG.
In step 33, it is determined whether the detected voltage V detected by the voltage detector 10 is higher than the rated voltage E, and if it is higher (correction rotational speed F is set to 0), the process returns to the main routine in step 33. If the detection voltage V is lower than the rated voltage E,
In step 34, the difference between the detected voltage V and the rated voltage E is multiplied by the correction coefficient k to calculate the corrected rotational speed F, and in step 35, the process returns to the main routine. In the main routine, in step 36, the correction value adding means 12 adds the corrected rotation speed F to the reference target rotation speed N to calculate the corrected target rotation speed R. Then, in step S4, the rotational speed adjusting actuator 8 controls the rotational speed adjusting unit 9 of the engine 1 to a position corresponding to the corrected target rotational speed R via the actuator drive circuit 21. As a result, the rotation speed of the engine 1 is set to a high value, the output voltage drop due to the performance drop of the engine 1 and the generator 2 is corrected, and the output voltage is properly maintained at the rated voltage E.

FIG. 1 is an operation system diagram of the inverter type engine generator, FIG. 2 is a correlation diagram of a load voltage of the generator and a target rotation speed, and FIG. In the figure, an engine 1 is linked with a generator 2, and an output voltage of the generator 2 is converted into a DC voltage by a rectifier circuit 3 and then a predetermined frequency (for example, 50 Hz or 6 Hz) is obtained by an inverter 4.
The output voltage is converted to an AC voltage of 0 Hz) and output from the output terminal 5. Further, the output current of the output circuit 20 of the generator 2 is the current detector 6 and the output voltage is the voltage detector 10.
, So that they can be detected respectively. Then, based on the load detection current C detected by the current detector 6, at 7,
The reference target rotation speed N of the engine 1 is calculated, and the rotation speed adjusting portion 8 of the engine 1 is operated by the rotation speed adjusting actuator 8 via the actuator drive circuit 21.
Is configured to be controlled and operated at a position corresponding to.
The reference rotation speed calculation means 7 is a part of the function of the microcomputer 22, has an internal memory that stores the data of the engine rotation speed indexing curve D shown in FIG. 2, and detects the load of the current detector 6. The values N1 to N10 of the reference target rotation speed N are calculated from the values C1 to C10 of the current C. Further, the microcomputer 22 has a correction value calculation means 11
And the respective functions of the correction value adding means 12 are added. Then, the values N1 to N10 of the reference target rotation speed N
On the other hand, the deviation of the actual rotation speed detected by the rotation speed sensor 24 attached to the crankshaft 23 of the engine 1 is calculated,
The rotational speed adjusting section 9 is operated by the rotational speed adjusting actuator 8 so that the deviation becomes zero, and the actual rotational speed of the engine 1 is brought close to the values N1 to N10 of the reference target rotational speed N.
Further, only when the detection voltage V detected by the voltage detector 10 is lower than the rated voltage E, the correction value calculation means 11 calculates the correction rotation speed F, and the correction value addition means 12 calculates the correction rotation speed F. The corrected target rotation speed R is calculated by adding it to the reference target rotation speed N, and the rotation speed adjusting section 9 is set to the position corresponding to the corrected target rotation speed R by the rotation speed adjusting actuator 8.

する必要があるのは言うまでもない。When the engine 1 is controlled at the corrected target rotation speed R and the output voltage of the generator 2 becomes stable, the corrected target rotation speed R is replaced with the reference target rotation speed N in the memory. It is also possible to store it as a new reference target rotation speed N. In this case, when the detected voltage V detected by the voltage detector 10 is higher than the rated voltage E,
The correction value adding means 12 adds the corrected rotation speed -F to the reference target rotation speed N to calculate the corrected target rotation speed R again, and controls the rotation speed adjusting unit 9 with the rotation speed adjusting actuator 8. Needless to say, it is necessary to maintain the output voltage of the generator 2 at the rated voltage E.
