Research on Automatic Control Method of Power Regulation System of Xi'an Pulsed Reactor

There are some differences between the software and hardware of the digital power regulation system and the previous analog systems, thus a new method for the automatic power regulation needs to be studied. The control model of digital power regulation system is built and the basic idea of the automatic control method is proposed. The key technical issues including avoiding short period problem and enhancing the stability of the motion of the control rod are studied. The automatic control method of the digital power regulation system is designed through iterative calculations. The simulation code of Xi'an Pulsed Reactor(XAPRSC) is applied to verify the design method, and the results show that the new method meets the design index and is beneficial to the operation safety of Xi'an Pulsed Reactor.
