Online courses in colleges and universities need professional equipment and settings for students to experience the operating environment, but the real equipment is expensive and the operating experimental conditions are limited, which results in the knowledge expression defects of professional courses. The development of virtual simulation laboratory can help the laboratory to realize the practice environment of 3D virtual simulation, which requires the integration of new technologies such as virtual reality into teaching. This paper adopts the latest GL3D Web design technology and Three. js related open source frameworks to design the system. With the help of the virtual laboratory, the whole experimental process and experimental results can be fed back to the virtual laboratory users in real time through three-dimensional visualization, which further improves the effect of experimental teaching and reduces the pressure of experimental work. Through virtual simulation technology, this paper builds a flexible teaching platform to promote the teaching function of controlling virtual equipment with the help of physical control system. © 2023 SPIE.

A design method based on deep reinforcement learning is proposed for the problem of designing a model tracking control law with anti-disturbance capability. Firstly, the basic control structure based on the model tracking method is determined. Then an open source high fidelity arithmetic aircraft dynamics model is selected to carry out the control law design through simulation. The intelligent body model is built by deep deterministic policy gradient algorithm (DDPG), and the state quantity, control quantity and reward are set according to the target model tracking control problem, and the intelligent body is trained. The trained intelligent body is simulated and tested to verify its model tracking control capability with high anti-disturbance capability. By comparing with the control effect of traditional PID algorithm under perturbation, it is further demonstrated that the intelligent body trained based on deep deterministic policy gradient algorithm for flight control can achieve the model tracking control target with good anti-disturbance capability at the same time. © Beijing HIWING Scientific and Technological Information Institute 2024.

District heating based on fossil energy is an important source of carbon emissions, and district heating of nuclear power plants is one of the ways to alleviate this problem. Since the 1960s to 1970s, international studies on nuclear energy for district heating have been conducted, and these studies have mainly focused on 2nd-generation nuclear power plants. At present, there are fewer units for district heating based on 3rd-generation passive nuclear power technology. In this paper, we analyze the impact of district heating on NSSS (Nuclear Steam Supply System) control system of passive nuclear power plants (AP1000 and CAP1400), including reactor control system, rapid power reduction, steam dump control system, and feedwater control system, taking Haiyang nuclear power plant and Shidaowan nuclear power plant for example. And the corresponding I&C modification schematic is given according to the analysis. © 2023 by JSME.

As an important part of boiler, the stability of water level determines the combustion quality and equipment safety of the whole boiler system. As for drum water level, it affects whether its water level is maintained at normal water level, feed water flow, superheated steam outlet flow and boiler combustion system, among which the main influencing factors are feed water flow and superheated steam outlet flow. Aiming at these two main influencing factors, the three-impulse control system is controlled by PLC as the main controller and PID regulation. In order to get closer to the engineering practice, this study selects SMPT-1000 (Advanced Multi-functional process control training System) as the experimental platform. In the SIMATIC PCS7 process control system of this platform, a three-impulse control scheme of drum water level is designed, and the three-impulse control system is compared with the two-impulse control system. The adjustment time of the three impulses is shorter than that of the former, which proves that the response speed of the control system is faster. © 2023 ACM.

The new power system at the station level is the phased product of the large-scale and high-proportion penetration development of wind and solar new energy. The source network load storage system with the station area as the smallest adjustable unit is constructed by using energy storage +. Different from the traditional substation area system, the architecture of the new power system at the substation area level becomes extremely complex due to the change of access terminal attributes, interaction relationship and various business types. In order to systematically describe the new power system architecture at the station district level, this paper first combs and summarizes the relevant literature at home and abroad, and summarizes the literature related to the current substation District, wind and new energy access and energy storage system regulation. Secondly, from the perspectives of demand differences, common functional requirements and non functional requirements, the requirements of station area level new power system under different application scenarios are classified and analyzed in detail. Then, a new power system for different scenarios is designed, which is divided into local equipment layer, edge control layer, station management layer and centralized control layer from bottom to top, and the functions of each layer are described in detail. Taking Zhangjiajie scenery storage and charging comprehensive energy demonstration project as an example, this paper expounds the ways of terminal data access, transmission and visualization under the framework of Taiwan district level new power system, so as to provide reference for the networking of other similar projects. Finally, the research contents of this paper are summarized, and the contents that need further research in the future are prospected. (c) 2023 Published by Elsevier Ltd.

To improve the low-speed stability of the space optical scanning servo system, a method to estimate speed using the least-squares fit based on FPGA was proposed. The multi-order least-squares polynomial is used to fit the position tracking curve, and the derivative was used to calculate the speed of the optical scanning mechanism. Through simulation and experiment, the stability of this method and the traditional M -method speed measurement method under low-speed working conditions were compared. Results show that the new method has improved accuracy while low-speed working conditions and improved stability by more than 4 arcsec (3σ).
