Percentage difference from nominal voltage < ±3% Short term flicker severity, PST < 1.0 Long term flicker severity, PLT < 0.8 Max ratio of negative phase sequence to positive phase sequence voltage < 1% 2) Protection Abnormal Voltage Response Minimum Holding Time (s) - requirement Maximum Tripping Time (s) - requirement Abnormal Voltage Range (% of nominal voltage) V < 50 50 ≤ V < 88 110 < V < 120 > 0.6 > 2.0 > 1.0 ≤ 1.6 ≤ 3.0 ≤ 2.0 The DER generating unit shall be capable of disconnecting from the transmission system if under or over voltage is detected at the connected person’s incoming switchboard or at the generating unit terminal. Depending on the abnormal voltage range, the generating unit shall remain in operation for a minimum holding time and disconnect before the maximum tripping time as specified above. Abnormal Frequency Response Operating Time Continuous operation Frequency Range (Hz) 47.5 ≤ f ≤ 52 47 ≤ f < 47.5 Remain in operation for at least 20s each time frequency falls below 47.5Hz. 3) Reconnection The DER system shall also cease to energize the transmission system for faults on the service connection between the DER system to the PCC. The DER system may reconnect to the transmission system 1 minute after the voltage and frequency at its connection point have recovered and remained within the ranges listed as follows: (a) Frequency within 49.8Hz and 50.2Hz; Page 2 of 3 Ver 6.0 (b) Transmission network voltage within ±3% of the nominal value or distribution network voltage within ±6% of the nominal value. 4) Inverter Specification Reactive power control mode: Q(V) Control 4 If other mode is selected, please indicate the details: _____________________________________________ 4. By signing below (Part IV), you agree that the above reactive power control mode will be set before inverter(s) energization, in compliance with the requirements stipulated in the Transmission Code. For more details on the settings, please refer to Transmission Code F12. PART V: CHOICE OF BACKUP SCHEME FOR EMBEDDED GENERATION (DER) (Must be filled for Intake Voltage at HT and above) We understand that consumers connected at HT and above with embedded generation (DER) are required to choose a backup scheme 5 for their service connection. Please prepare a Supplemental Agreement for Consumer based on the backup scheme of their choice (please tick one backup scheme): ☐ 1) Summation Scheme (please tick one metering option): ☐ Installation of Summation meters (Where there are no generation meters installed, summation meters will be provided by SPPA) ☐ Generation meters (If generation meters are already installed, there is no need to install additional summation meters as the generation meters can double up as summation meters) ☐ Solar Generation Profile (Applicable for contestable consumers who have embedded generation (PV) below 10 MWac and are registered with SPS/EMC) ☐ 2) Capped Capacity Scheme ☐ 3) Extended Capped Capacity Scheme 5. For more details on backup scheme, please refer to Handbook on “How to Apply for Electricity Connection” (Appendix 39). PART VI: DECLARATION OF COMPLIANCE TO SPPG’S TECHNICAL REQUIREMENTS I, (LEW No.: ), (Name) the undersigned Licensed Electrical Worker (LEW) for the DER installation at the above premises, declare that I have evaluated and confirmed that the DER system complies with the above, including requirements as per “Technical Requirements of Distributed Generation (DG) and New Extra High Tension (EHT) Connection”.
