ABSTRACT:
This paper puts forward a method to design the user-defined
component based on the user-defined modeling environment CBuilder of RTDS simulator. And also develops the user-defined component model with algorithm described
by C language, visual graphics appearance, and the component function. And it
generates the dynamic link library which has the same execution efficiency as that
of the included model of RTDS. This paper takes the IEEE type EXST1 static
excitation system as an example to build the user-defined component. The
closed-loop tests on the user-defined component and the included one of RTDS
are performed to examine the accuracy of the proposed method. By comparison,
the test results show that the external characteristics of the user-defined
component and the included model of RTDS are basically the same in the
initialization process, the step process of the terminal voltage reference
value and the case of the large disturbance.
