What Is a Power System Simulation?

Power system simulation refers to the use of virtual reality technology to virtualize real-world industrial plants and equipment in computers, and the use of database technology, data acquisition and monitoring and control technology to transfer the operating state parameters of production equipment to the virtual power plant system in real time , Can realize the query management of the device in the three-dimensional virtual scene.

Right!

Power system simulation refers to the use of

1) Simulation of power plant construction process and power generation process

The power station simulation system is a simulation system constructed by applying simulation technology to power stations. At present, it is mainly used for personnel training. There are many titles, such as power plant simulation system, power plant simulation training system, power plant simulation training system, power plant simulation trainer, power plant simulation trainer, power station simulator, power plant simulator, and so on. The development of modern power plant simulation technology has provided a strong material foundation for the safe production of the power industry; the universal application of power plant mechatronics, the level of automation has continued to increase, and new topics have been continuously proposed for power plant simulation technology. The rational application of power plant simulation technology and power safety production have been inseparable.

Since the 1950s, several major developed countries in the West have begun to develop nuclear reactors and nuclear power plant operation simulation trainers due to the need for safe operation of nuclear power plants. By the 1970s, a considerable number of nuclear power plant training and simulation centers had been established, which had played a very important role in improving the operating level of operators. China initially did not have its own simulation technology. By the early 1980s, the Department of Thermal Engineering of Tsinghua University began to develop its own power plant simulation training system, and in 1982 completed the development of China's first power plant simulator.

As the capacity of the unit generator set becomes larger and larger, the system becomes more and more complex, and higher requirements are placed on its economic operation and safe production. The simulation system is the best way to achieve this goal. The simulation system can optimize the operation process and train operators. The power station simulation system has become a necessary equipment in the construction and operation of power stations. Most of the early training simulators include simulations of DCS systems, but they are often relatively simple, and they are basically "black box" models, which are very different from actual systems. Its main role is to train crew operators. The modern simulation system can not only be used to train operating personnel, but also to perform DCS configuration and training for thermal control personnel.

In addition, for the new power generation technology, there are corresponding simulators, such as circulating fluidized bed power plant simulator, supercritical unit power plant simulator, integrated coal gasification combined cycle ) power plant simulator, waste incineration power plant simulator , and so on.

The modern power plant simulation technology has greatly developed compared to the earlier power plant simulation, and has incomparable advantages. However, with the advancement of technology and practice, performance is constantly improving, and the fields and service functions involved will be more extensive.

(1) At present, the minimum simulation step size of power plant simulation reaches 10 milliseconds. Whether to achieve a more accurate simulation cycle will be a research direction.

(2) Due to the powerful simulation function, the simulator has been included in the essential content of the electric power training field before taking up the job. With the development and practice of technology, power plant simulation systems will be more widely used in simulation experiments in the aspects of safety management, accident analysis, economic operation, and optimization of power production.

(3) Modeling theory and method are still the key research directions to promote the development of simulation technology. It is the basis for the sustainable development of system simulation. ^[1]
