OVERVIEW

HSM300 Synchronous Module is specially designed for genset automatic parallel. On the basis of the parameters, the module automatically tests the conditions of paralleling (volt difference, frequency difference and phase) and sends parallel signal when the conditions meet parallel requirements. HSM300 Synchronous Module is used for the occasions that gens synchronize to bus. The module is brief to operate, easy to install and widely used for ship genset and land genset.

PERFORMANCE AND CHARACTERISTICS

• Suitable for 3-phase 4-wire, 3-phase 3-wire, 2-phase 3-wire, single phase 2-wire systems with frequency 50/60/Hz;
• Adjustable potentiometer allows for set main parameters of synchronizing;
• The operating parameters can be set via upper computer test software. LINK port should be connected to upper computer via SG72 module (USB to LINK);
• 4 relays output, 2 relays are used for UP output, DOWN output, 1 SYNC relay is used for sync close output, 1 STATUS relay is used for status output after close;
• 1 INH “inhibit sync close output” digital input, when the input is active and gens synchronize with bus, the SYNC indicator will illuminate and sync close relay is inhibited to output;
• Widely power supply range DC(8~35)V;
• 35mm guide rail mounting;
• Modular design, pluggable terminal, compact structure with easy installation.

FUNCTION DESCRIPTION

HSM300 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 its switch close response time can be set, the module can be used for gensets of various source powers.
Thresholds of over voltage, under voltage, over frequency and under frequency of gens and bus can be set via monitoring software of PC. When the module detects voltage  and frequency of gens and bus are normal, it will begin to adjust speed. When pressure difference, frequency difference and phase difference are within pre-set value, it will send synchronize 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.

Table 8 Five Steps for Relay Output Regulation Function

large adjust error, ascending  frequency relay will continuously be activated.
2| Up Pulse| Raise the pulse| System activates regulatory function, then ascending  frequency relay will eliminate deviation in the pulse way.
3| No Reg.| No regulation| No regulation in this area.
4| Down pulse| Drop down the pulse| System activates regulatory function, descending frequency  relay will eliminate deviation in the pulse way.
5| Fix down signal| Continuously drop down
signal| System activates regulatory function, descending frequency relay will continuously be activated.

As showing in fig.3, when adjusting deviation XP exceeds pre-set value, the relay will be in the continuous activate status; when XP is not large, the relay will work in pulse  way, and the pulse will become shorter along with the deviation became smaller. 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

10.1 OUTPUT AND EXPAND RELAYS
All outputs are relay contact output type. If need to expand the relays, please add freewheel diode to both ends of expand relay’s coils (when coils of relay have DC current) or  add resistance-capacitance return circuit (when coils of relay have AC current), in order to prevent disturbance to controller or others equipment.
10.2 WITHSTAND VOLTAGE TEST
CAUTION! When relay had been installed in control panel, if need the high voltage test, please disconnect relay’s all terminal connections, in order to prevent high voltage into relay and damage it.
