FKGA22-DF8000 large customer electric load management terminal
1．technique features:
1)Adopt high-speed 32 bit embedded processor and operation system,
and 4mb MFS
2)Communication channel adopts high-speed of industry GPRS/GSM/CDMA
module. Support
TCP/UDP/SMS wireless network communication mode.
3)Embedded high speed and precision of alternating voltage current
collection module, high precision sampling and energy measurement
on real-time.
4)Support communication regulation of master station: <>.
<>, and communication regulation adopts share mode. Make
users’ convenience to develop diverse of relative application and
expanse regulation depend on what they requires.
5)Support communication regulation of energy meter:
DL/T645-1997(part of regulations). Landis+gyr B/D. Red-phase. ABB.
Clou. HND. Actaris. IEC1107 and wasion. Regulation of meter adopts
share mode, based on expand and increase depends on what locale
requires.
6)Support online upgrade of local/remote software, and amend
terminal parameters.
7)excellent electromagnetism compatibility performance, resist
high-voltage pulse, strong magnetic field and static, lighting
strike surge, possess the scope of stronger temperature
self-adapting.
8)Three-phase power supply, load management terminal will work
normally when break off one-phase on three-phase three-wire and one
or two-phase on three-phase four-wire.
9)Low power consume
2. main functions:
1)ARM:
Support DL/T-645, IEC1107, and regulation of meter are used
generally. Terminal also supports at least two type of regulation
on meter connection at the same time, and supports master station
remote upgrade for terminal meter regulation storeroom. ARM through
RS485 port, and to record various real-time, curve, day, month of
meter data. Energy measurement and alternating sampling of
self-terminal also possess various real-time data, curve data,
statistic data on day and month. Terminal can keep saving at least
9 meters of 60 days curve data.
2)energy measurement:
Measure bi-directional active energy, four-quadrant reactive energy
and bi-directional reactive energy can be set the sum of any two
phases.
3)loading monitor and control:
Collect current of three-phase on real-time, three-phase voltage,
and three-phase of active power, reactive power, apparent power and
power factor.
Provide grid running situation such as over voltage, phase missing,
terminal power cut, reverse phase sequence voltage, electricity
overload, current anti-polarity, and current imbalance this kind of
information.
Statistic voltage passing rate and overtime limited
Support local power factor control: period of time, day-off of
factory and temporal power limited. Terminal also can set time or
power factor fixed value of users. It tests automatically and
alerts when power factor over limit in a valid time, power factor
fixed value can be detected if over the setting of period alert,
but terminal will follow the valid setting to brake sequentially.
Support remote control directly, also for keeping power and delete
function.
4)Telecommunications:
Support mode of GPRS, CDMA, message and dial, achieve remote
transmit for data; communication module adopts wireless chip of
some essential firms; part of tekecommunications circuit designed
by modularize, easy maintenance and electrification replacing;
users only replacing the communication module if they want to
change the type of communication network, do not need to change the
whole terminal.
5)local display:
Terminal adopts back-light, long-life, anti-static, prevent
ultraviolet radiation of LCD, and the scope of working temperature
is minus 25 to 75 degree. Chinese characteristic to display
measurement data, count and record parameter, also display several
of measurement value, and switch different parameter when user
press operation button.
6)abnormal alert:
Testing automatically with judge terminal and abnormal meter
depends on different alert reports on real-time, and immediate
report to master station and displayed on LCD. Record locale of
important data, analyze and manage them when meet all abnormities.
Terminal and meter self-diagnose alert: clock abnormal, low power
inside the battery, and measure mutual inductance been changed by
multiplicator.
Measure loop running situation alert: phase missing, phase
breaking, reverse phase sequence voltage and current anti-polarity.
Meter set parameter before leave factory, running parameter alert:
pulse parameter of meter and period of tariff been changed, maximum
demand can be reset.
Terminal automatic analyze and manage alert with relative
measurement: current imbalance, data current imbalance, stop
running, running fast, fail communication, and switch alarm for
door of cabinet.
7)security defend policy:
Terminal adopts the mode of countersign and password for different
communication channel and important operation with security
protection and hardware prote
