Diesel generator and solar synchronization procedure [with diagram]

The difference between the synchronization of a grid-tied solar power plant with a grid and with a diesel generator is that the grid needs net-metering to estimate the exported solar surplus power whereas a diesel generator requires ZED Advance to protect the generator from solar surplus power.

In this blog, I will tell you the step-by-step procedure of synchronizing diesel generators and solar.

before jumping into the procedure of synchronizing the diesel generator with solar here is the list of the items required.

1. ZED Advance: To protect diesel generators from the surplus power of solar.

2. Transfer Switch: To isolate diesel generator from the grid, when grid power is available.

3. Set of Current Transformers: For Load Feedback to ZED Advance.

4. 10 Core Cable: For connecting ZED Advance with current transformers.

5. 3 Core Cable: For voltage feedback to ZED Advance.

6. CAT 5 or CAT 6 Cable: To connect ZED Advance with Solar inverters and Local Area Network.

7. LAN Connection: For connecting ZED Advance with the internet [for remote monitoring of generator, grid, and solar power plant].

Now here is the Six step procedure to synchronize solar with Diesel Generator.

Step#1: Install a (set) of current transformer(s) at the coupling point of the diesel generator and load. For the measurement of power drawn from DG.

Step#2: Connect the output of a current transformer(s) to the DG PV controller [ZED Advance] via a 10-core, 1.5-sqmm cable.

Step#3: Take one power source (voltage source) before the coupling point of DG and load to ZED Advance via 3 core, 1.5 Sqmm cable. For the internal power requirements of DG PV controller and voltage reference for power analysis.

Step#4: Connect grid-tie (on-gird) PV inverter (solar inverter) with DG PV controller [ZED Advance] via LAN (CAT 6 or CAT 5 ) cable.

Step#5: Connect ZED Advance to local internet via LAN (CAT 6) cable. For the online monitoring of the PV plant, DG, and Grid.

Step#6: In the ZED Advance, set the sharing point of load on DG SET at 30% of DG capacity, to keep DG SET minimum of 30% loaded.
