“…With the VLE, students can perform such experiments as controller design and system identification of the multivariable process. Actually, the power plant simulators [24] are virtual laboratories as well, except that they aim at operator training instead of control system design. A plug-in free online three-dimensional (3D) interactive laboratory, based on networked control system laboratory (NCSLab) framework, is deployed in Wuhan University for control engineering experiments [16].…”

Programmable logic controller (PLC) is always set as a professional course of automation-related majors in Chinese universities and colleges. Abundant experiments are required to ensure that the students are sufficiently trained to get qualified practical skills and engineering abilities. The evaluation of abundant PLC experiments is a heavy and time-consuming task, and it is hard to grade an experiment result precisely and fairly. In this paper, a cloud-based automatic evaluation system for PLC experiments is accordingly proposed to deal with the above problems. Aliyun is employed to build the system platform. During experiments, client threads on the cloud will be scheduled to accesses the on-site S7-1500 PLCs through OLE for process control (OPC) UA protocol. Further, an innovative sectionbased experiment management method is proposed to make the system open, configurable, and thus extendable. The system relieves the hard work of the teachers on experiment evaluation and provides accurate evaluation conclusions. In contrast, the students can get more comprehensive feedback information and advice from the system to better understand the experiments and the behind principles. The cloud-based framework, the standard protocol as OPC UA, and the configurability of the system can be good references for other relevant systems.

“…The training of plant operators is a crucial aspect for the safe and economic operation of a plant. In [67] the development of a boiler and a power-plant models are the heart of a training simulator for plant operators. The plant was coal-fired and consisted of six boilers, with a common steam collector and six turbines of 250 t/h steam capacity, and rated output of 60 MW e .…”

Since the widespread deployment of non-dispatchable, intermittent, and highly variable power production from renewable energy sources (RES), the demand for flexible power production has been steadily growing. As new-built dispatchable power plants have not been very quickly adapted to the emerging flexible operation, this task has been addressed by existing plants as well. Existing solid-fuel thermal power plants have undergone an extensive study to increase their flexible operation. Thermodynamic process-modeling tools have been extensively used for plant modeling. Steady- and transient-state simulations have been performed under various operating regimes, supplying valuable results for efficient power-plant operation. Flexibility aspects regarding low-load operation and steady operational conditions are mostly investigated with steady-state simulations. Flexibility aspects related to variation over time such as ramping rates are investigated with transient simulations. The off-design operation is mainly attributed to the existing fleet of power plants, struggling to balance between their former operational schemes as base and/or medium-load plants. However, off-design operation is also considered for new plants in the design phase and is included as a simulation aspect. Process modeling turns out to be a proven tool for calculating plant flexibility and predicting extreme operating conditions, defining further steps for a new operational scheme, drafting accident mitigation control procedures or, furthermore, provisioning more complex and cross-field future tasks. A review of the off-design aspect as a simulation approach is undertaken and presented in this work. Finally, challenges and future perspectives for this aspect of solid-fuel thermal power plants are discussed.

“…As discussed in detail by Lazarova-Molnar et al (2016), most past research on emulators involved fault detection diagnosis (FDD), which is treated in Annex 25 following Annex 17 (IEA 1999). However, very few studies have focused on the training or educational uses of emulators (Neuman 2011(Neuman , 2012Serra et al 2017). Kelly and May (1990) reported in detail an emulatorbased method for testing BEMS, outlining the major BEMS functions and hardware and software configurations available at that time and describing the evaluation criteria, conditions, and results of BEMS testing.…”

A "performance gap" arises when the actual value of building energy consumption during the operational phase deviates from the value predicted using simulation during the design phase. One cause of this performance gap is that operation is not ideal, as assumed in the simulation, and the control of the heating, ventilating, and air conditioning (HVAC) system is not optimized. These problems occur because the operator has not been trained sufficiently and/or the building automation system is not working as intended by the developer. Both problems are fundamentally caused by the fact that the quality of building operation cannot be quantitatively evaluated by comparison with other buildings because a building is a heterogenous, single-item product. To address the performance gap problem, we developed a method for quantitatively evaluating building operation using a precise simulation based on a thermal environment emulator. The emulator software was developed using the BACnet protocol as an interface to the real world and includes an occupant behavior model to enable the assessment of operation in terms of thermal comfort as well as energy performance. In this paper, we report on the program and network structure of the proposed emulator. In addition, we show the concrete results of changing the operational control, and we assess changes in energy performance and comfort from the perspective of Pareto efficiency.
