“…A variety of control methods have been proposed for flexible operation, e.g. sliding mode control [243], LQG [244], and nonlinear state feedback [245]. With the current state of technology, load-following operation of nuclear power plants is achievable albeit at an economic cost due to operation at partial capacity [246,247].…”

“…It should be noted that the HEX dynamics may be ignored when it has the bypass control mechanism [2]. The turbine system can be expressed with 1 ( ) 1 T t G s s (10) where (in seconds) is the time constant of turbine system. The generator-load model has the following transfer function 1 ( ) 2 GL G s D Hs (11) where D is the load damping factor (in megawatts per Hz) and H represents inertia constant (about 2 to 9 seconds).…”

“…The load following control studies for nuclear power plants have mostly been carried out in steam turbines due to dominancy of pressurized and boiling water reactors [6], [7], [8], [9], [10], [11], [12], [13]. Recently, some studies have also been demonstrated for dynamic modeling, control and transient analysis in gas turbine nuclear plants [14], [15], [16], [17].…”

Advanced nuclear power plants are currently being proposed with a number of various designs. However, there is a lack of modeling and control strategies to deal with load following operations. This research investigates a possible modeling approach for advanced nuclear power plants in order to provide an assessment way to the concept designs. The modeling approach covers linear and nonlinear reactor modeling and linear modeling of heat exchanger-turbinegenerator systems. Numerical results are presented on an example molten-salt type nuclear power plant system to demonstrate the validity and effectiveness of the modeling approach.

Growing electricity requirement and the serious pollution caused by burning petroleum and coal give the current rebirth of nuclear energy industry. State observation is one of the key and basic technologies of system monitoring which is very necessary to the safe and effective operation of today's nuclear reactors. Since nuclear reactors are complex and nonlinear systems, it is quite necessary to design a nonlinear state-observer with high-performance for nuclear reactors. A dissipation-based high gain filter (DHGF) is presented for nonlinear systems in this paper, and robustness analysis is also given. The DHGF is then applied to the state-observation for a nuclear heating reactor (NHR), and simulation results show the feasibility of the DHGF.
