2.2 Overview

Function

The SmartLogger monitors and manages the PV power system. It converges all ports, converts protocols, collects and stores data, and centrally monitors and maintains the devices in the PV power system.

Network Application

The SmartLogger applies to a PV power system. It supports the following:



Local operations on the SmartLogger using the mobile phone app through the built-in WLAN



RS485 networking, which enables the SmartLogger to connect to:

− Huawei devices such as inverters and PID modules

− Third-party inverters, environment monitoring instrument (EMIs), box-type

transformers, and power meters that use the standard Modbus-RTU protocol

− Power meters that use the DL/T645 protocol

− Devices that use the standard IEC103 protocol



PLC networking, which enables the SmartLogger to connect to inverters and the PID-PVBOX.



Ethernet, 2G, 3G, or 4G networking, which allows the SmartLogger to connect to a network management system (NMS) that uses the Modbus TCP or IEC104 protocol

When using the IEC104 protocol,4G/3G/2G networking is not supported.

Parameter

Description

RCD enhancing

RCD refers to the residual current of the inverter to the ground. To ensure device and personal safety, RCD should comply with the standard. If an AC switch with a residual current detection function is installed outside the inverter, you need to enable this function to reduce the residual current generated during inverter running, thereby preventing the AC switch from misoperations.

Reactive power output at night

In some specific application scenarios, a power grid company requires the inverter to perform reactive power compensation at night to ensure that the power factor of the local power grid meets requirements.

This parameter is available only when Isolation is set to Input ungrounded (with TF).

Strong adaptability

If the value of Power grid short circuit capacity/power plant installed capacity is less than 3 and the power grid impedance is too high, the power grid quality will be affected and the inverter may be unable to run properly. Set Strong adaptability to Enable.

Power quality optimization mode

If Power quality optimization mode is set to Enable, the output current harmonics of the inverter will be optimized.

PV module type

Specifies the type of PV module. The PV module type determines the inverter shutdown time. If concentration PV modules are shaded, the power may drop to 0 abruptly and the inverter shuts down. The energy yield would be affected since it takes too long for the power to recover and inverter to restart.



If PV module type is set to Crystalline or Film, the inverter will run properly and will not shut down if PV modules are blocked.



When concentration PV modules are used:

− If PV module type is set to CPV 1, the inverter

can restart quickly in 60 minutes if PV modules are shaded and the input power decreases abruptly.

− If PV module type is set to CPV 2, the inverter

can restart quickly in 10 minutes if PV modules are shaded and the input power decreases abruptly.

Crystalline silicon PV compensation mode

This parameter reduces the DC voltage of PV modules to the PE by reducing the impedance of the inverter input side to the PE, thereby effectively reducing PID effect of PV modules.

Set this parameter to P-type output for P-type PV modules and N-type output for N-type PV modules.

The standards of certain countries and regions require that the inverter must shut down after the communication is interrupted for a certain time.

If Communication interrupt shutdown is set to Enable and the inverter communication has been interrupted for a specified time (set by Communication interruption duration), the inverter will automatically shut down.

Communication interruption duration

Specifies the duration for determining communication interruption, and is used for automatic shutdown for protection in case of communication interruption.

Communication resumed startup

If this parameter is enabled, the inverter automatically starts after communication recovers. If this parameter is disabled, the inverter needs to be started manually after communication recovers.

The SmartLogger can connect to third-party devices that support IEC103, such as the relay protection or monitoring device like the box-type transformer. The protocol information points vary depending on vendors. Therefore, you need to obtain a protocol information file in .cfg format from Huawei and import the file into the SmartLogger for successfully connecting to a custom device.

The supported device types are IEC103 device 1 to IEC103 device 5. The corresponding configuration file names are iec103_equip_custom_1.cfg to iec103_equip_custom_5.cfg. Multiple devices of the same type can be connected.

Parameter

Description

Active power control

Set this parameter to Enable.



To ensure that the SmartLogger will deliver scheduling commands to the connected inverters, you must enable active or reactive power control before adjusting the active or reactive power for a PV plant.



If you disable active or reactive power control, the SmartLogger will not deliver scheduling commands to the connected inverters and the inverters will retain their status after the previous change.

6.4.2 Setting Active Power Control

If the PV plant has requirements of power limitation, the power grid scheduling personnel should limit the active power or disable all the active power for the PV plant, that is, to enable the active power derating mode.



"√" indicates low level. When connecting to DI–, the four DI+ ports of the SmartLogger are low-level ports. If not connected, the ports are high-level ports.



The percentage levels of DI1–DI4 should differ from each other. Otherwise, an abnormal command will be generated.



If the actual input DI signal is inconsistent with that configured on the WebUI, the SmartLogger controls the inverter to work at full load and the Abnormal Active Schedule alarm is raised.

Parameter

Description

Start time

If the inverter needs to run with specified maximum power in certain periods of a day, add setting records based on site requirements.

When multiple time points are set, the inverter will run with the maximum power specified for the time point that is earlier than and the closest to the current system time. For example, if you add 00:00:00 and 12:00:00 on the WebUI and the current system current is 14:30:00, the inverter will run with the maximum power specified for 12:00:00.

Percentage(%)

Parameter

Description

Active power control

Set this parameter to Enable.

Active power control mode

Set this parameter to Remote scheduling. The SmartLogger parses the scheduling command delivered

by the upper-layer NMS to valid instruction data that can be identified by the inverters in the PV plant and delivers the data to all inverters connected to the SmartLogger.

As the Remote scheduling mode has a higher priority, the SmartLogger automatically changes Active power control mode to Remote scheduling after receiving a scheduling command from the upper-layer NMS.

Schedule strategy

The value can be Disable, Strategy 1, or Strategy 2.



Disable: The SmartLogger controls the inverter to work at full load and will not receive scheduling commands sent by the NMS.



Strategy 1: Open-loop scheduling policy. That is, the SmartLogger evenly allocates the power value from the scheduling and delivers the average value to each inverter, which then operates with the specific power. The adjustment value delivered by the SmartLogger is constant. If Adjustment coefficient is set, the power value will be sent to the inverter after being multiplied by the preset coefficient.



Strategy 2: The customized function is provided for a site. Set Overshoot, Adjustment period, and Adjustment deadband based on the scheduling requirements of the site.

Remote Scheduling

The NMS or independent power adjustment device sends scheduling commands over the communications port that works with Modbus-TCP or IEC104, without the need of user configuration or operation. The SmartLogger can automatically switch between scheduling modes and send scheduling commands.

6.4.3 Setting Reactive Power Control

Large-scale PV plants are required to adjust the voltage at the grid-tied point.
