SmartGen HSM340 Synchronous Module

OVERVIEW

HSM340 Synchronous Module is specially designed for automatic parallel of 400Hz system genset. According to the pre-set parameters, the module can automatically complete genset parallel condition detection (volt difference, frequency difference and phase) and send parallel signal when the conditions are well prepared.
HSM340 Synchronous Module applies to the occasion where it can synchronize generator to the bus. The module is simple to operate, easy to install and widely used on ship genset and land genset.

PERFORMANCE AND CHARACTERISTICS

Main characteristics are as below:

  • Suitable for 3-phase 4-wire, 3-phase 3-wire, 2-phase 3-wire, single phase 2-wire power system with 400Hz frequency;
  • Adjustable potentiometer allowing to set the main parameters about synchronization;
  • Operating parameters can be set via PC test software. LINK port should be connected to computer via SG72 module (USB to LINK);
  • 4 relay outputs, 2 of which are used for speed UP output and DOWN output; 1 SYNC relay is used for sync close output, and 1 STATUS relay is used for status output after close;
  • 1 INH “inhibit sync close output” digital input; when it is active and gens synchronizes with bus, the SYNC indicator will illuminate and sync close relay is inhibited to output;
  • Wide power supply range DC(8~35)V;
  • 35mm guide rail mounting;
  • Modular design, pluggable terminal, compact structure with easy installation.

FUNCTION DESCRIPTION

HSM340 Synchronous Module is to synchronize generator to bus. When voltage difference, frequency difference and phase difference are within pre-set value, it will send synchronization signal to close gens switch. Because switch close response time can be set, the module can be used for gensets of various source powers.
Users can set over voltage, under voltage, over frequency and under frequency thresholds of gens and bus via PC monitoring software. When the module detects voltage and frequency of gens and bus are normal, it will begin to adjust speed. When voltage difference, frequency difference and phase difference are within pre-set value, it will send synchronization signal to close gens switch.

RAISE/DROP SPEED RELAY OUTPUT CONTROL

When deviation area XP is set as 2Hz, the working principle of raise/drop speed relay is as follows.

SmartGen-HSM340-Synchronous-Module-3

Relay output regulation function can be divided into 5 steps.

Table 8 – Term Description

No. Range Description Note
1 Fix Up Signal Continuous raise signal Adjusting activation. For too large

derivation,

relay has to activate continuously.

2| Up Pulse| Raise the pulse| System adjusting activation. Relay works in

pulse to eliminate derivation.

3| No Reg.| No regulation| No regulation in this area.
4| Down Pulse| Drop down the pulse| System adjusting activation. Relay works in

pulse to extinguish derivation.

5| Fix Down Signal| **** Continuous drop signal| System adjusting  activation.  For  too  large

derivation, drop relay will remain in activating status.

As Fig.3 shows, when adjusting deviation XP exceeds pre-set value, the relay will be in continuous activating status; when XP is not large, the relay will work in pulse. In Up Pulse, much smaller the derivation is, much shorter the pulse becomes. When regulator output value is close to “No Reg.”, pulse width will be the shortest value; when regulator output value is nearest to the “Down Pulse”, pulse width will be the longest value.

INSTALLATION NOTES

OUTPUT AND EXPAND RELAYS
All outputs are relay contact outputs. If it needs to expand relay, please add freewheel diode to both ends of expand relay’s coils (when coils of relay has DC current), or add resistance-capacitance loop (when coils of relay has AC current), in order to prevent disturbance for controller or other equipments.

WITHSTAND VOLTAGE TEST
CAUTION! When controller has been installed on control panel, if it needs to do high voltage test, please disconnect relay’s all terminal connections, for the purpose of preventing high voltage entering relay and damaging it.
