DIgSILENT PowerFactory Tutorial: Composite Model Frame for DSL Modeling | Lecture 46 This lecture presents the essential first step in developing custom DSL (Dynamic Simulation Language) models in DIgSILENT PowerFactory: the creation of a Composite Model Frame. The tutorial demonstrates a practical two-block configuration that imports external time-series data for active power (P) and reactive power (Q) from a text file and injects it into a grid-connected general load. The step-by-step workflow covers: • Grid preparation with a busbar and general load element • Construction of the Composite Model Frame, including definition of slots for an external file reader (ELM_file) and a controllable load (ELM_load) • Signal connection between the file block outputs (P, Q) and the load block inputs (P_external, Q_external) • Integration of the Composite Model in the Data Manager, assignment of measurement files, and import of structured time-series data • Configuration of an RMS simulation and creation of plots to validate that the load follows the prescribed external P and Q profiles By mastering the Composite Model Frame, users gain the capability to incorporate measured or custom external data into dynamic studies. This technique is fundamental for advanced applications such as custom load modeling, SCADA-driven simulations, stability analysis with realistic input profiles, and the development of user-defined controllers. The tutorial is designed for power system engineers, researchers, and graduate students who wish to progress from basic load-flow studies to flexible, data-driven dynamic modeling in PowerFactory.
