Street Lighting with Twilight Sensor

Symbol

Use

The street lighting component is used to calculate load curves from automatically switching lights. The automatic switching is based on the ambient brightness from the environment connector.

Parameters and Connectors

The lighting is controlled automatically (i.e. on and off) dependent on surrounding light conditions. To avoid permanent on and off switching at twilight, two different illumination limits (i.e. a hysteresis) are defined.
When the ambient brightness falls below radianceEnable, the lighting switches on, when the ambient brightness rises over radianceDisable, the lighting switches off.

Thus the radianceDisable value has to be higher than the value of radianceEnable.

The model symbol shows the parameterized power horizontally at the bottom and the switch-on threshold vertically on the mast.

Model Background

The energetic characteristics of the model are solely based on the parametrized electric power consumption. This power is distributed equally across all three phases of the three-phase electrical connection. The result variable Pel only represents the power on a single phase.
