Conditional Voltage and Current Thresholds in Electrical System (tSys.i16VltBase = 230)
This code snippet demonstrates a conditional block that sets specific voltage and current thresholds when the variable 'tSys.i16VltBase' equals 230. Here's a breakdown of the code:
if (230 == tSys.i16VltBase)
{
tSys.i16Vlt_Ac_High1 = 253.6F;
tSys.i16Vlt_Ac_High1Hys = 253.0F;
tSys.i16Vlt_Ac_High2 = 287.5F;
tSys.i16Vlt_Ac_High2Hys = 253.0F;
tSys.i16Vlt_Ac_High3 = 290.5F;
tSys.i16Vlt_Ac_High3Hys = 253.0F;
tSys.i16Vlt_Ac_Low1 = 184.0F;
tSys.i16Vlt_Ac_Low1Hys = 196.0F;
tSys.i16Vlt_Ac_Low2 = 103.5F;
tSys.i16Vlt_Ac_Low2Hys = 196.0F;
tSys.fBus_Vlt_High = 445.0F;
tSys.fBus_Vlt_HighHys = 432.0F;
tSys.fBus_Vlt_Low = 300.0F;
tSys.fBus_Vlt_LowHys = 400.0F;
tDc.fBus_VltLmt = 430.0f;
tDc.fBus_SoftVlt = 380.0f;
tSys.f110OverLoad = tSys.fActivepower * 0.005F; // Current overload 110%
tSys.f130OverLoad = tSys.fActivepower * 0.005909F;
tSys.f150OverLoad = tSys.fActivepower * 0.006818F;
}
- Variables: The code assigns values to variables likely related to voltage and current thresholds within an electrical system.
- AC Voltage Limits: Variables like 'tSys.i16Vlt_Ac_High1', 'tSys.i16Vlt_Ac_High2', 'tSys.i16Vlt_Ac_High3' and their corresponding hysteresis values define upper limits for AC voltage. Similarly, 'tSys.i16Vlt_Ac_Low1' and 'tSys.i16Vlt_Ac_Low2' define lower voltage limits.
- Bus Voltage Limits: 'tSys.fBus_Vlt_High' and 'tSys.fBus_Vlt_Low' set the upper and lower limits for bus voltage, while their 'Hys' counterparts likely represent hysteresis values.
- Overload Thresholds: The code calculates current overload thresholds at 110%, 130%, and 150% of 'tSys.fActivepower' (active power). These values are probably used to trigger protective measures in the system if the current exceeds these limits.
This code snippet likely forms part of a larger program or system that monitors and controls an electrical circuit or device. The specific values assigned to these variables will be determined by the design requirements and specifications of the system they belong to.
