摘要
针对电厂希望对机组进行全范围、全工况、实时、连续仿真的迫切要求,提出采用高级过程仿真软件(APROS)作支撑平台开发集操作培训、工程分析研究于一体的多功能仿真机。指出火电版本APROS提供的图形化电气模型库中只有母线、开关、发电机、变压器、线路、负荷几种简单的元件,为弥补其不足,部分电气设备如励磁等可采用数学函数模块或逻辑模块组合建模。文中励磁建模是根据励磁系统的物理特性,建立由比例-积分-微分3个函数叠加作为主要环节的励磁系统数学传递函数。发电机同期并网时要求冲击电流要小,并网后发电机能迅速进入同步,因而文中建立的同期模型具备调节功能使得并网断路器两端的电压有效值、电压频率、相角3个分量的差为零。
To meet demands of full-scope ,all-condition ,real-time and continuous simulation of unit, APROS（Advanced PROcess Simulator） is adopted as the support platform to develop a multifunction simulator,which integrates operation training and project analysis. Its graphical electrical model library（thermal power version） supplies only a few simple elements such as bus,switch, generator, transformer,line and load. Several electrical devices such as exciter can be modeled by the combination of mathematical function modules and logic modules. The excitation model is expressed by a mathematical transfer function based on physical characteristics of the excitation system,mainly including proportional- integral-differential functions. To realize small impulse current and quick generator parallel-in,the established synchronization model has the function to regulate differences of voltage virtual value, frequency and phase between two ends of the parallel-in switch to zero.
