Case 1 :
20kV MV Voltage Drop
Context:
– During the T&C (Testing & Commissioning), a voltage drop tripped the generator.
– A PQ (Power Quality) analyzer was installed to determine the RCA (Root Cause Analysis) and corrective actions.
Added value:
Power quality measurements helped determine the true root cause (load impact due to inverter ramp-up). This allowed for a comprehensive RCA report and validation from the end-customer. The issue was resolved simply by adjusting the inverter parameters.
Case 2:
Grid analysis on inverters
Context:
Analyseo implemented T&C (Testing & Commissioning) analysis on the inverters. The tests included dynamic tests and load tests (0 ⬌ 100%). As part of this process, a PQ (Power Quality) analyzer was installed to monitor the output of the inverters, with more than 28 inverters tested.
Added value:
Although disturbances were found during testing, it was demonstrated that they remained acceptable and within ITIC tolerances. A standardized process was established to meet program requirements (28 inverters in 2 months).
Case 3:
Black Building Test
Context:
The client wanted to implement an upgrade or BBT. With this in mind, the operation needed to be performed without any impact on the critical load. Analyseo therefore installed a PQ (Power Quality) analyzer on the end-client’s servers for the entire duration of the construction work.
Added value:
The network was continuously analyzed with ongoing reports provided to the client. This final report was delivered to the end-client, confirming that no impact on the critical load occurred.
