During the operation of a trough solar power station, the stability of the outlet temperature of the thermal conductor is an important control objective for the safe and reliable operation of the power station. Due to the structural characteristics of the collector tube, the outlet temperature characteristics of the trough collector have large inertia and large delay, so the outlet temperature control problem is complicated. In order to solve this problem effectively, a dynamic mathematical model of MW trough solar power collector circuit is constructed in this paper, and a temperature control system is constructed at the collector outlet. A step prediction controller for the outlet temperature of trough solar power collector circuit is proposed. Simulation experiments were carried out based on MATLAB/Simulink platform. The simulation results show that, for the groove heat collecting loop, under the disturbance of irradiation, heat conduction oil inlet temperature and ambient temperature, the stepped predictive control system has shorter adjustment time, smaller overshoot, better robustness, and significantly improved control effect compared with the traditional PID control system. The proposed predictive controller can well cope with the situation of heat conduction oil overtemperature and heat conduction oil flow fluctuation at the outlet of heat collecting field, which is conducive to the safe and stable operation of the trough heat collecting field.

槽式太阳能光热电站运行过程中,集热回路的导热工质出口温度稳定是电站安全可靠运行的重要控制目标。由于集热管的结构特点,槽式集热器出口温度具有大惯性、大延迟、出口温度控制问题复杂等特性。为此,构建了兆瓦级槽式太阳能集热回路的动态数学模型,并在集热器出口构建了温度控制系统,提出一种槽式太阳能发电集热回路出口温度的阶梯式预测控制器,并基于MATLAB/Simulink平台进行了仿真。仿真结果表明,对于槽式集热回路,在辐照、导热油入口温度和环境温度扰动情况下,相较于传统PID控制系统,阶梯式预测控制器调节时间更短,超调量更小,鲁棒性更好,控制效果提升明显。所提出预测控制器能很好地应对集热场出口导热油超温及导热油流量波动频繁的情况,有利于槽式集热场的安全稳定运行。

槽式太阳能光热电站运行过程中,集热回路的导热工质出口温度稳定是电站安全可靠运行的重要控制目标。由于集热管的结构特点,槽式集热器出口温度具有大惯性、大延迟、出口温度控制问题复杂等特性。为此,构建了兆瓦级槽式太阳能集热回路的动态数学模型,并在集热器出口构建了温度控制系统,提出一种槽式太阳能发电集热回路出口温度的阶梯式预测控制器,并基于MATLAB/Simulink平台进行了仿真。仿真结果表明,对于槽式集热回路,在辐照、导热油入口温度和环境温度扰动情况下,相较于传统PID控制系统,阶梯式预测控制器调节时间更短,超调量更小,鲁棒性更好,控制效果提升明显。所提出预测控制器能很好地应对集热场出口导热油超温及导热油流量波动频繁的情况,有利于槽式集热场的安全稳定运行。

During the operation of a trough solar power station, the stability of the outlet temperature of the thermal conductor is an important control objective for the safe and reliable operation of the power station. Due to the structural characteristics of the collector tube, the outlet temperature characteristics of the trough collector have large inertia and large delay, so the outlet temperature control problem is complicated. In order to solve this problem effectively, a dynamic mathematical model of MW trough solar power collector circuit is constructed in this paper, and a temperature control system is constructed at the collector outlet. A step prediction controller for the outlet temperature of trough solar power collector circuit is proposed. Simulation experiments were carried out based on MATLAB/Simulink platform. The simulation results show that, for the groove heat collecting loop, under the disturbance of irradiation, heat conduction oil inlet temperature and ambient temperature, the stepped predictive control system has shorter adjustment time, smaller overshoot, better robustness, and significantly improved control effect compared with the traditional PID control system. The proposed predictive controller can well cope with the situation of heat conduction oil overtemperature and heat conduction oil flow fluctuation at the outlet of heat collecting field, which is conducive to the safe and stable operation of the trough heat collecting field.
