The PQ Diagram is a graphical representation of a limit curve of available reactive power as a function of actual active power generation. It also indicates the target setpoint and the actual operating point. It is typically used to operate synchronous generators. The limit curve can be modified during runtime, for example, when limits change due to temperature changes. It is a pure graphical module. There is also a project example available (2025-10-13_14-47-18 pq_diagram_demo.zip).
