State of Rajasthan - Subsection

Section 6(3) in Rajasthan Electricity Regulatory Commission (Transmission Licensee's Standards of Performance) Regulations, 2004

(3)Voltage Variation Index. - This performance standard shall be achieved during Final Stage (Level-3).Voltage variation Index representing the degree of voltage variation from nominal value of over a specified period of time shall be computed by the RVPN.N∑ (Vi - Vs) 2
| VVI =| 100Vs| x square root of| i=1N
Where Vi = RMS value of voltage in KV at ith hour in the period for which VV I is computed Vs= the nominal voltage in RMS value of the system i.e. 400 KV, 220, KV and 132KV etc. as may be applicable at the inter-connection point.N = number of hourly measurements over the specified period of time.The Voltage Variatic Index (VVI) on annual basis shall not exceed the limit of 1% for voltage levels of 220 kV, 132 kV and 66 kV and in respect of 400 kV nominal voltage the WI shall not exceed the 1.125%.RVPN shall determine is index separately for higher and lower than normal system voltages. Defective metering/abnormal data will be discarded while computing the index.
