摘要
针对Petri网模型具有建模灵活、系统性能分析能力强等特点,以及有载调压变压器的控制器具有离散动作、延时调节等动态特性,提出1种新的有载调压变压器的控制器Petri网模型。首先分析有载调压变压器的混杂调节特性;然后,利用Petri网理论建立有载调压变压器的控制器离散模型;最后,分别在无功功率充足和无功功率不足的情况下,针对1个简单电力系统对有载调压变压器的Petri网模型进行仿真,并分析有载调压变压器的离散调节对系统运行的影响。仿真结果表明,建立的Petri网模型能够准确地描述有载调压变压器的调节特性以及对系统运行的影响。
In connection with such characteristics of Petri net model as flexible modeling and strong ability in system performance analysis,as well as dynamic characteristics of on-load tap-changing transformer controller,such as discrete action,delay adjustment and so forth,the paper sets forth a new Petri net model of on-load top changer controller.The paper first analyzes mixed adjustment of on-load tap-changing transformer,afterwards it establishes discrete model for on-load tap-changing transformer controller by employing Petri net theory;finally,it respectively simulates Petri net model of on-load tap-changing transformer of a simple power system under circumstances of both sufficient reactive power and insufficient reactive power and analyzes impact of discrete adjustment of on-load tap-changing transformer on system operation.The simulation result shows that the established Petri net model can accurately describe the regulating characteristics of on-load tap-changing transformer and the impact on system operation.
