Table 7-2 Hot standby mode parameter settings
Parameter Description Entry/Exit
Condition
Application
Scenario
Zero-power
operation
No hot standby. The
Smart PCS is
operating with zero
power. The Smart PCS
responds in real time
after receiving a
power scheduling
command.
- Scenarios where fast
response to power
scheduling is
required, such as
frequency
regulation scenarios.
Seamless hot
standby
After the Smart PCS
enters the hot standby
state, the PWM wave
transmission is
stopped, but the grid-
tied relay on the AC
side is not
disconnected. If the
Smart PCS receives
the power scheduling
command, it takes
about 10 ms to exit
the hot standby mode
and respond to the
power scheduling.
In the seamless hot
standby scenario, the
AC port of the Smart
PCS generates a
certain amount of
reactive power. The
system automatically
selects a certain
number of Smart PCSs
to compensate for the
system reactive power.
In this scenario, the
no-load loss of the
Smart PCS is very low.
● Delayed
entry after
the power
scheduling
instruction is
0.
● Exit after
receiving a
non-zero
power
scheduling
command.
Scenarios where low
standby loss and
fast response to
power scheduling
are required, such as
peak shaving and
frequency
regulation scenarios.
