1 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.

8.1.1 Controlling Rectifier Output Voltages

Principles

If System Control Mode is Manual, you can set rectifier output voltages.

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.

8.1.2 Controlling Rectifier Output Currents

Principles

You can limit the rated rectifier output current based on site requirements.

If System Control Mode is Automatic, the SMU adjusts the maximum rectifier output

current within the rated current range.

If System Control Mode is Manual, the SMU enables the maximum rectifier output current

to always equal the rated output current.

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

SMU02B




107

If the power system experiences an exception, such as battery loop disconnection, battery

overtemperature, AC faults, and rectifier faults, all rectifiers exit the hibernation state and try

to hibernate again after the time preset by Hibernation Stop Duration expires.

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 provides three disconnection modes, as described in Table 8-5.

8.4 Lead-Acid Battery Management

8.4.1 Charging Management

If the AC input to the power system is normal and meets load requirements, rectifiers supply

DC power to loads and lead-acid batteries. If the AC input to the power system is abnormal or

rectifiers cannot supply DC power, lead-acid batteries supply power to loads. After the AC

input or DC output is restored, rectifiers supply DC power to loads and lead-acid batteries.

SMU02B




118

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.

Figure 8-23 shows the battery charge process.

Figure 8-23 Battery charge process

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.

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.

SMU02B




127

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.

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.

8.4.7 Presence and Balance Detection

The SMU detects battery presence and balance from the following aspects:

Presence

Middle point voltage balance

Balance of each battery

Current balance

Presence Detection

The SMU checks whether batteries are present by using a signal cable for monitoring battery

middle point voltages. If a battery is stolen, the SMU generates a Battery Not Detected alarm,

reminding users of taking measures immediately.

The number of battery strings to be detected depends on the power system type. The SMU

detects the presence of a maximum of six battery strings.

Figure 8-48 shows the hardware connections. Table 8-18 describes the parameters.

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.

SMU02B




187

Figure 8-111 Power line graph

This function takes effect only when the D.G. is running.

Cable Connections

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).

Figure 8-116 Alternation of the D.G. and batteries

SMU02B




191

You are advised to use batteries with large capacity and optimal cycle performance when

using the D.G.-mains-battery alternation function, because the alternation is frequent.

You can alternate the D.G. and batteries in DOD mode and time mode. The alternation

conditions vary based on the mode, as shown in Figure 8-117.

Figure 8-117 Conditions for D.G.-mains-battery alternation

Cable Connections

Figure 8-118 shows the signal cable connections among the D.G., ATS, and UIM.

8.7 Programmable Logic Controller

The SMU performs the flexible Programmable Logic Controller (PLC) function.

You can select any signals (such as those indicating DC undervoltage, D.G. operating, and AC

power failures) and perform logical operations on them, namely, AND, OR, NOT, >, and <,

and then send calculation results to dry contacts. Figure 8-130 shows the PLC conceptual

diagram.
