Overview

1.1 Introduction The SMU is a small-sized high-end monitoring module that monitors and manages Huawei box-type and cabinet-type power systems. You can access the SMU over Huawei NetEco, third-party element management systems (EMSs) that support the Simple Network Management Protocol (SNMP), or a WebUI to remotely manage power systems. By configured with the user interface module 02C (UIM02C) or UIM02D (MUS01A), the SMU provides sensor ports, an RS485 port, dry contact inputs, and dry contact outputs for managing the environment inside the cabinet and reporting alarms. Figure 1-1 shows an SMU, Figure 1-2 shows a UIM02C, and Figure 1-3 shows a UIM02D. Figure 1-4 shows the connections between the SMU, UIM, and system interface board. Figure 1-5 shows the network between the SMU, power system components, and EMSs. Figure 1-1 SMU

If System Control Mode is Automatic, you cannot set rectifier output voltages. Instead, the SMU adjusts rectifier output voltages. The output voltage must be higher than the value of DC Undervoltage Threshold (45.0 V by default). Otherwise, if the system voltage drops below DC Undervoltage Threshold, the value of System Control Mode changes to Automatic, and the preset output voltage becomes invalid.

8.2 Energy Conservation Management 8.2.1 Intelligent Rectifier Hibernation The rectifier efficiency increases in proportion to the load power. If the total load power is low, certain rectifiers can hibernate to improve the load power of running rectifiers and increase the rectifier efficiency. This facilitates energy conversation. In addition, rectifier service life is prolonged because rectifier runtime is reduced. Figure 8-11 shows a rectifier efficiency curve. Figure 8-11 R4850G1 efficiency curve

The SMU starts and hibernates rectifiers based on the loading capacity of the power system. If the load power decreases, the SMU hibernates certain rectifiers. If the load power increases, the SMU starts rectifiers to meet load power requirements. To ensure that all rectifiers deteriorate to the same degree, the SMU hibernates different rectifiers each time based on their real-time efficiency and runtime. See Figure 8-12. Figure 8-12 Rectifier hibernation periods

8.3 Power Segment Management If the AC input to the power system becomes abnormal, batteries start to power loads. To prolong the operating duration of primary loads and avoid reducing the battery lifespan due to overdischarge, the SMU controls BLVD and LLVD based on preset disconnection parameters. After the AC input is restored, the SMU connects BLVD and LLVD routes again. The power distribution design of the power system allows the SMU to perform power segment. You can set disconnection parameters based on load type to disconnect secondary loads first, and then primary loads. This effectively extends the backup time for primary loads.



After the BLVD route is disconnected, the power system does not power loads.



You can disable BLVD, but batteries may be damaged due to overdischarge.

The SMU enables batteries to be switched between float charging and equalized charging by adjusting the output voltage. 

Float charging: The SMU compensates the electricity consumed by self-discharge after full charge.



Equalized charging: The SMU fully charges batteries rapidly by increasing the output voltage. During equalized charging, the SMU limits the rectifier output current to avoid battery damage caused by over large charge current.

8.4.2 Fast Charging You can start fast charging when necessary. After fast charging is started, the SMU limits the charge current based on the fast charge current coefficient. The maximum charge current can be 0.50 C10.

SMU02B User Manual


After fast charging is complete, the SMU resumes normal battery charging management.

During fast charging, batteries generate much heat and the battery temperature rises, which deteriorates the battery performance and shortens the battery lifespan. You are advised to exercise caution when using fast charging in non-emergencies. Table 8-10 describes the fast charging mode. Table 8-10 Manual fast charging mode description Mode

8.4.3 Temperature Compensation To reduce the effect of ambient temperatures on batteries, prolong the battery lifespan, and maintain a reliable charge current, the SMU adjusts the output voltage based on the optimal operating temperature, present battery temperature, and temperature compensation coefficient. If the ambient temperature rises, the SMU decreases the output voltage. If the ambient temperature decreases, the SMU increases the output voltage. The tolerance is ±2 V.

Temperature compensation is valid only when batteries are being charged in float mode or hibernating. For details about intelligent battery hibernation, see 8.4.9 Intelligent Battery Hibernation. The SMU does not perform temperature compensation if the battery temperature sensor is disconnected or faulty. Figure 8-31 shows the temperature compensation control logic.

8.4.4 High and Low Temperature Alarm and Protection As the battery temperature rises, the SMU generates an alarm and protects batteries by taking the measures that you selected, to avoid battery damage due to continuous working at high temperatures. The alarms and protective measures are as follows: 1.

If the battery temperature exceeds the value of High Temperature Alarm Threshold, the SMU generates a high temperature alarm.

2.

If the battery temperature exceeds the value of Very High Temperature Alarm Threshold, the SMU takes a protective measure that you selected. You can select any of the following measures: −

Lower the battery charge voltage.

−

Disconnect batteries.

−

Do nothing.

If the battery temperature is below the value of Low Temperature Alarm Threshold, the SMU generates a low temperature alarm.

8.6 D.G. Management The SMU manages a D.G. from the following aspects: 

Power Limitation This function applies to a D.G. with light power. The power supply to loads takes precedence over the power supply to batteries.



Alternation of the D.G. and batteries This function applies to energy-saving scenarios. The SMU alternates the D.G. with batteries to improve the power efficiency of the D.G. and therefore enhance the power system efficiency.



Scheduled D.G. shutdown This function applies to the scenarios requiring low noise. The SMU shuts down the D.G. on schedule to reduce the noise effect on the residents around.

8.6.1 Power Limitation The D.G. supplies power to DC loads and batteries over rectifiers. If the power system cabinet is configured with an AC air conditioner, the D.G. also supplies power to the AC air conditioner. Figure 8-110 shows the D.G. supply conceptual diagram. Figure 8-110 D.G. supply conceptual diagram

The SMU limits the total output power of rectifiers by limiting the battery charge current to ensure that the total power of the power system does not exceed the rated D.G. power. Figure 8-111 shows the power line graph.

8.6.2 D.G.-Mains-Battery Alternation The SMU intelligently selects the power supply from the mains, D.G., and batteries. If the mains is normal, the SMU uses the power supply from the mains and shuts down the D.G. If there is no mains, the SMU alternates the D.G. and batteries. The D.G. loading capacity is in inverse proportion to fuel consumption. The SMU alternates the D.G. and batteries to increase the D.G. loading capacity, decrease the fuel consumption, and reduce the operating expense (OPEX).
