励磁装置在线测试数字仿真系统的研究

Research on Digital Simulation System of Online Test for Excitation Device

同步发电机励磁调节装置的参数最终整定和动态实验通常是在真实机组上完成的,这种试验方法对机组的冲击性很大,有时甚至很危险。针对这一问题,研发了基于"单机-无穷大系统"的励磁调节器测试软件包,虚拟了包括同步发电机及网络元件在内的真实机组系统,并且可与励磁装置共同构成虚拟发电机—励磁调节器的闭环控制回路,完成励磁装置实时在线的半实物仿真测试。能实现方便在线修改测试系统数据参数和实时显示励磁调节器测试结果的功能,具有可靠、安全、方便的特点,对提高励磁装置的品质有重要意义。

The parameter final setting and dynamic experiments of excitation control system are usually implemen- ted with real synchronous generators. In a sense, this approach is dangerous because it will bring a high impact to generator. To solve this problem, based on one machine infinite bus system, a simulation software package for excita- tion regulator test system is developed including the synchronous generator and other network elements that exist in re- al system. By this method a generator - excitation regulator closed control loop is formed and an exciter online half - real simulation test system is established. It can implement the function that is for easy online modification of testing system data parameters and the real - time display of excitation regulator test results. It has reliable, safe and con- venient features which has an impact on improving the quality of the excitation device.
