Title: Power unit
Inventor: NAKANO KATSUAKI
IPC: G05F1/10
Filed: 1980-08-30
Abstract: PURPOSE:To reduce a load applied to an equipment at the time of short-circuiting and make the equipment compact by a method wherein the amount of an output voltage reduced when impedance exceeds the load for actual use is detected to extract a short-circuiting current. CONSTITUTION:The output from an invertor 3 is fetched out of output terminals 8a, 8b as a DC output. When load impedance becomes smaller than a load for actual use (region indicated by shade lines), a load line moves from point C into a constant-current region. When the load impedance still decreases, the output voltage also decrease in porportion to that of the load impedance. When the output voltage decreases beyond point A, an output voltage detection circuit 6 detects that decrease and sends a control signal to an output current detection circuit 7. The control signal follows the load diagonally because of a control circuit 2, rapidly reducing a load shorting current.

Title: Thermal power plant equipped with stored steam power generation system
Inventor: HAMAMATSU TERUHIDE
IPC: F01K3/04
Filed: 1981-07-31
Abstract: PURPOSE:To permit the stored steam power generation system to be operated in high efficiency by arranging a mixed pressure turbine which is driven by the steam stored in an accumulator and feeding steam into the high-pressure stage in initial operation and feeding steam into the low-pressure stage when the steam pressure lowers below a prescribed value. CONSTITUTION:When the demand for electric power increases in the daytime, a steam regulating valve 22 is controlled to open side by the opening signal (y) from a valve controller 28, keeping a steam regulating valve 24 in closed state. Therefore, the hot water stored in an accumulator 9 is decompressed by opening the steam regulating valve 22 and is evaporated itself to form steam, which passes through a check valve 23, and flows into the high-pressure stage of a mixed pressure turbine 20, which drives a power generator 14. The pressure of the steam which is generated in the accumulator 9 reduces gradually, and when the pressure lowers to a certain value, the steam regulating valve 24 is controlled to open side and the steam regulating valve 22 is closed. Therefore, the low-pressure steam flows into the low-pressure stage of the mixed pressure turbine 20, which drives the power generator 14, and steam is discharged into a condenser 15.
