ASV100 := RB14 AND ALT01 # Supervise remote control with ALT01
ASV101 := RB15 AND PLT07 # Supervise remote control with PLT07
ASV201 := ASV100 OR ASV101 # Store desired control in ASV201
# Remote control 2
ASV100 := RB18 AND ALT09 # Supervise remote control with ALT09
ASV101 := RB19 AND PLT13 # Supervise remote control with PLT13
ASV202 := ASV100 OR ASV101 # Store desired control in ASV202
Note that the remote bits used here must be asserted for at least one
second for this to work. If they are pulsed, the automation equations
may not see their change of state.
SELOGIC Control
Equation Math
Variables
SELOGIC control equation math variables are math calculation storage results.
As with protection and automation SEL
OGIC control equation variables, there
are separate storage areas for protection and automation math calculations.
The quantities of SEL
OGIC control equation math variables available in the
relay are shown in Table 14.10.
Use math variables in free-form programming to store the results of math
calculations as arguments in math calculations and comparisons.
Example 14.5 illustrates SEL
OGIC control equation math variable usage.
EXAMPLE 14.5 SELOGIC Control Equation Math Variables
The equations below show free-form SEL
OGIC control equation
programming examples that use SEL
OGIC control equation math
variables. Each line has a comment after the # that provides
additional description.
PMV01 := 378.62 # Store 387.62 in PMV01
PMV09 := 5 + VAFM # Store sum of 5 and A-phase voltage in kV in PMV09
You can use SELOGIC control equation math variables more than once
in free-form programming. Use AMV010 in the following SEL
OGIC
control equations to calculate intermediate results.
# Determine if any phase voltage is greater than 13 kV
# A-phase
AMV010 := VAFIM # VA in secondary volts
ASV010 := AMV010 > 13 # Set if greater than 13 kV
# B-phase
AMV010 := VBFIM # VB in secondary volts
ASV011 := AMV010 > 13 # Set if greater than 13 kV
# C-phase
AMV010 := VCFIM # VC in secondary volts
ASV012 := AMV010 > 13 # Set if greater than 13 kV
# Combine phase results
ASV013 := ASV010 OR ASV011 OR ASV012
