- 摘要：
- In this paper, a dynamic model of the Canadian supercritical
water-cooled reactor (SCWR) is developed to
examine its dynamics for potential control system design
and analysis. The model development is based on fundamental
mass, energy, and momentum conservation equations
of major components within the Canadian SCWR
operating at supercritical condition. A full set of nonlinear
dynamic equations is first derived, from which linearized
models are obtained. The linearized models are
validated against the full-order nonlinear models in both
time domain and frequency domain. The open-loop dynamic
characteristics of the Canadian SCWR are investigated
through extensive simulations. Steady-state and
dynamic couplings among different inputs and outputs
are examined using relative gain array and Nyquist plots,
and adequate input-output pairings are identified. Crosscoupling
at different operating conditions is also evaluated
to illustrate the nonlinear behaviors of the system.
The developed dynamic model provides a necessary platform
for systematic investigation in the control system
design and analysis of the Canadian SCWR.
