RULE Fill in Y, which means the generator maintenance scheduling
shall satisfy the ES rules; if fill in 0 or left blank, it means the
generator maintenance scheduling does not have to be tested
by ES rules
PERIORTY Manually given maintenance priority, optional
RERIOD Generator maintenance period (days)
SHIFT Margin before and after the maintenance period (days)
PRETIME Last maintenance start time (YY-MM-DD)
FINISH Last maintenance finish time (YY-MM-DD)
DUR1 Time (days) required for the first maintenance after the last
maintenance
DUR2 Time (days) required for the second maintenance after the
last maintenance, optional
DUR3 Time (days) required for the third maintenance after the last
maintenance, optional
DUR4 Time (days) required for the fourth maintenance after the last
maintenance, optional
COST Production expenses or coal consumption, optional
MAN Manpower required for maintenance, optional

(3) Area maintenance capacity restraint card (RA card), which gives the name of the area to
limit the maintenance capacity, maintenance restraint capacity, and time range where the
card works (see Table 3.5).

Table 3.5 Contents of RA card

Identifier Contents

RA RA, denoting the area maintenance capacity
restraint card
AERA Name of area
ACAP Upper limit of area maintenance capacity (MW)
A-START Start date (YY-MM-DD) of area maintenance capacity
restraint, optional
A-END End date (YY-MM-DD) of area maintenance capacity
restraint, optional
Note: If A-START and A-END are left blank, it indicates the area maintenance capacity restraint
card works in the whole GMS study period. If dated YY-MM-DD, the area maintenance capacity
shall be restrained in the given time range.

(4) Maintenance time nonoverlapping (for power plants) card (RP), which can restrain all unit
maintenance time from overlapping in the given power plant, with card contents shown in
Table 3.6.
