本发明实施例涉及配电网工程技术领域，尤其涉及一种基于ADPSS的仿真模型生成方法及系统。Embodiments of the present invention relate to the technical field of distribution network engineering, and in particular, to a method and system for generating a simulation model based on ADPSS.
背景技术Background technique
近年来以风力发电、光伏电池和微型燃气轮机等为代表的分布式发电(Distributed Generation，DG)技术的发展己成为人们关注的热点。在此基础上建立微电网能够充分发挥DG的作用，同时也是提高供电可靠性、改善电能质量，保证电网安全运行的一种十分有效的途径。微电网接入DG后，伴随大量电力电子器件的应用，大型DG的启动、输出功率的短时剧变，以及与系统中电压反馈控制设备相互作用都可能对微电网造成冲击，引起大量谐波和电压闪变等问题。In recent years, the development of Distributed Generation (DG) technology represented by wind power, photovoltaic cells and micro gas turbines has become a hot spot of people's attention. On this basis, the establishment of microgrid can give full play to the role of DG, and it is also a very effective way to improve the reliability of power supply, improve power quality, and ensure the safe operation of the power grid. After the microgrid is connected to the DG, with the application of a large number of power electronic devices, the startup of the large DG, the short-term drastic change of the output power, and the interaction with the voltage feedback control equipment in the system may impact the microgrid, causing a large number of harmonics and Voltage flicker, etc.
实时仿真是研究电力电子、电力系统复杂的工作过程、优化系统与运行的重要手段。电力系统全数字实时仿真装置(Advanced Digital System Simulater,简称ADPSS)是一种基于并行计算技术、采用模块化设计的电力电子、电力系统实时仿真系统，它既可以在普通PC机上进行离线仿真，也可以通过并行计算机与实际的电力电子器件连接而进行实时在线仿真。既可以对电力系统机电暂态或电磁暂态分别进行实时仿真，同时也可以对机电暂态和电磁暂态混合系统进行实时仿真。ADPSS在实时仿真过程中采用64位双精度浮点数运算，仿真精度高，其仿真精度与公认的离线分析软件MATLAB的仿真精度相当。由于直接采用商用的基于PC Cluster的硬件架构，当电网仿真规模增大时，只需增加CPU数目和增大内存容量即可，从系统的升级和扩展灵活性等方面有较好应用。Real-time simulation is an important means to study the complex working process of power electronics and power system, and to optimize the system and operation. The Advanced Digital System Simulater (ADPSS for short) is a real-time simulation system for power electronics and power systems based on parallel computing technology and modular design. Real-time online simulation can be performed by connecting a parallel computer with actual power electronic devices. Real-time simulation of electromechanical transient or electromagnetic transient of power system can be carried out separately, and real-time simulation of electromechanical transient and electromagnetic transient hybrid system can also be carried out. ADPSS uses 64-bit double-precision floating-point arithmetic in the real-time simulation process, with high simulation accuracy, which is comparable to that of the recognized offline analysis software MATLAB. Because the commercial PC Cluster-based hardware architecture is directly adopted, when the power grid simulation scale increases, it is only necessary to increase the number of CPUs and increase the memory capacity, which has better applications in terms of system upgrade and expansion flexibility.
目前，在微电网的规划和运行管理中，存在如下问题：当需要利用ADPSS对微电网规划方案进行仿真时，由于微电网规划方案的SIM模型文件不能直接被ADPSS使用，所以需要人工将SIM模型文件转换成符合ADPSS格式要求的中间文件，在通过中间文件利用ADPSS生成仿真模型，增加了人力物力成本的同时，导致仿真模型生成的效率低下。At present, in the planning and operation management of microgrid, there are the following problems: when it is necessary to use ADPSS to simulate the microgrid planning scheme, since the SIM model file of the microgrid planning scheme cannot be directly used by ADPSS, it is necessary to manually simulate the SIM model The file is converted into an intermediate file that meets the requirements of the ADPSS format, and the simulation model is generated by ADPSS through the intermediate file, which increases the cost of manpower and material resources, and leads to low efficiency of the simulation model generation.
因此，如何提高ADPSS中仿真模型生成的效率是现如今亟待解决的技术问题。Therefore, how to improve the efficiency of simulation model generation in ADPSS is a technical problem that needs to be solved urgently.
