摘要
在新形势下,为匹配新型电力系统需求,亟需对信息高度共享且需实时决策的电力二次系统进行建模与仿真.本文首次提出关联电力一次系统运行状态以实现电力二次系统仿真的设计方法.以功能描述复杂的智能变电站二次系统为研究对象,提出电力一次与二次系统仿真的关联方法,阐明其仿真实现框架、数据交互方法及数据同步管理,从而将一次系统的实际电气量数据传导至二次侧,解决二次系统仿真数据源问题.然后,进一步提出电力二次系统的仿真设计方法,基于面向对象统一建模语言(UML)提出其系统级交互设计、元件级类设计和模块级状态设计的方法,从而解析电气量数据在二次系统的传输交互处理转换全流程.最后,以220/110/10kV主变间隔110kV侧出口处短路故障场景为算例,结合主变差动保护方案,仿真验证所提方法的有效性.
Under the new situation,there is an urgent need to model and simulate the power secondary system which highly shares information and implements real-time decision-making,in line with the modeling and simulation requirements of new power systems.In this paper,design methods are proposed for the first time to achieve simulation of power secondary systems by correlating the operating status of the power primary system.The smart substation secondary system with complex functional descriptions is taken as the research object.First,an interrelated simulation method for power primary and secondary systems is proposed,and its simulation implementation framework,data interaction method,and data synchronization management are explained,which enables the actual electrical quantity data of the primary system to be transmitted to the secondary side,solving the problem of data source in the secondary system simulation.Then,a simulation design method for the power secondary system is proposed,incorporating system-level interaction design,component-level class design,and module-level state design based on the object-oriented unified modeling language(UML).Thus,the entire process of transmission,interaction,processing,and conversion of electrical quantity data in the secondary system can be analyzed.Finally,to validate the effectiveness of the proposed method,a case study is conducted using a short-circuit fault scenario at the 110 kV side outlet of the 220/110/10 kV main transformer bay,in conjunction with a differential protection scheme.
