Temperature Control of the 25kW Parabolic Dish-Stirling Engine System
Abstract: Nowadays, even
though many researchers continue to investigate and study about Parabolic Dish
based on Concentration Solar Power (CSP), the findings are not conclusive and
do not provide accurate evidence and proof on the potential of CSP development
in Malaysia. The missing link in the Parabolic Dish (PD) Stirling Engine system
modelled is the control systems, which vary the amount of working gas in the
Stirling engine. The temperature of the heater in PD system which has been
modelled is overheated and causes damage to the heater material, low output
efficiency, high thermal losses and effect to the lifespan of the PD system.
Therefore, the primary aim of this paper was to design a control system to
maximize output efficiency during a normal operation by maintaining the
heater/absorber temperature at the highest safe operating point and preventing
excessive range of threshold to prevent damage to the heater material.
