Parameter Description
Table 6-4 describes the PID module running parameters.
No. |
Parameter Name |
Function |
Parameter Value |
Description |
|---|---|---|---|---|
1 |
Offset mode |
Specifies the offset mode of the PID module. |
Disabled |
Set this parameter to Disable if the PID module is not required. |
N/PE |
Set this parameter to N/PE if the PID module is required to use voltage output from the inductor virtual midpoint N. |
|||
PV/PE |
Set this parameter to PV/PE if the PID module is required to use voltage output from the negative PV terminal. This mode is applicable only to SUN8000. |
|||
Automatic |
In the SUN2000, Automatic indicates the N/PE offset mode. |
|||
2 |
Output enabled |
Specifies whether the PID module output is enabled. |
Enable |
Set this parameter to Enable to allow the PID module output. |
Disable |
Set this parameter to Disable to forbid the PID module output. |
|||
3 |
PV type |
Specifies the type of the PV module used in the power station. For details about the PV module type, consult the manufacturer. |
P-type |
Set this parameter to P-type if the PV module type is P. In this case, the PID module output voltage is positive. |
N-type |
Set this parameter to N-type if the PV module type is N. In this case, the PID module output voltage is negative. |
|||
4 |
PV/PE offset volt. |
Specifies the DC voltage when the offset mode is set to PV/PE. |
0–200 V |
It is recommended that the offset voltage be set to a value ranging from 50 V to 200 V. |
5 |
Operation Mode |
Specifies whether the PID module is currently working in normal or commissioning mode. |
Commissioning |
In commissioning mode, if you need to set the output mode to PV/PE or N/PE, set Output enabled to Enable. The PID module delivers output voltages based on the value of Commiss. out.volt. NOTE:
Before the first power-on, to check whether the PID functions properly, it is recommended that Operation mode be set to Commissioning. |
Normal |
In normal mode, the PID module operates automatically after the PID module, inverter, and SmartLogger communicate with each other properly. |
|||
6 |
Commiss. out.volt |
Specifies the output voltage when the PID module works in commissioning mode. |
0–500 V |
It is recommended that the commissioning voltage for the 1000 V/1100 V inverter be set to a value ranging from 50 V to 400 V. NOTE:
After this parameter is set and the output from the PID module becomes stable, use a multimeter that is set to the DC position to measure the three-phase (A, B, and C) voltages of the power grid to the ground, and check whether the voltages are the same as the configured values. |
7 |
Max. DC voltage |
Specifies the PV-PE voltage when Operation Mode is set to Normal or Commissioning. |
500–1500 V |
If the PV module type is P, the parameter value indicates the highest DC voltage between PV+ and PE; if the PV module type is N, the parameter value indicates the highest DC voltage between PV- and PE. |
8 |
Maximum output voltage |
Specifies the maximum output voltage of the PID module when Operation Mode is set to Normal or Commissioning. |
0–500 V |
If the compensation mode is PV/PE, the parameter value indicates the highest DC output voltage between PV and PE; if the compensation mode is N/PE, the parameter value indicates the highest DC output voltage between N and PE. |
9 |
IMD access |
Specifies whether the PID module and insulation monitor device (IMD) can operate in cycle mode. |
Enable |
Select Enable if you allow the PID module and IMD to operate in cycle mode. Only the IMDs of mainstream suppliers such as DOLD and BENDER are supported, and the IMDs must have enabled dry contacts. |
Disable |
Select Disable if you forbid the access of IMDs. |
|||
10 |
Periodic PID runtime |
Specifies the operating time segment of the PID module when the PID module and IMD operate in cycle mode. |
60–480 min |
The IMD device is shut down when the PID module is operating. |
11 |
Periodic IMD runtime |
Specifies the operating time segment of the IMD when the PID module and IMD operate in cycle mode. |
15–480 min |
The PID module is standby when the IMD device is operating. |
12 |
IMD control dry contact |
Dry contact No. over which the SmartLogger controls the IMD |
DO1, DO2, and DO3 |
Set appropriate ports based on the cable connections between the IMD and the SmartLogger. |
