| 摘要 |
The present invention refers to a device for controlling the variable dead volume of a solar Stirling motor that forms part of a system for generating thermal solar electric energy for controlling the power and the speed of the engine considering the annual insolation, mechanical properties of the heater and the frequency and voltage limits for systems interconnected to the electric network. This control device is controlled by a logic control computer, which may be a microprocessor, microcontroller or a PLC, each one with the corresponding accessories. This computer has an especially designed program and is connected to the actuator of the control device (6), which uses a plunger that is attached to the central piece of the diaphragm, for displacing the same in order to suck or impel the fluid located in the chamber. |
