summation law
7.2.2 General approach based on the second
summation law
7.3 Stage 3: acceptance of higher emission levels
on an exceptional and precarious basis
8 Emission limits for distorting loads in HV systems
8.1 Stage 1: simplified evaluation of disturbance
emission
8.2 Stage 2: emission limits relative to actual
network characteristics
8.2.1 Assessment of the total available power
8.2.2 Individual emission limits
8.3 Stage 3: acceptance of higher emission levels
on an exceptional and precarious basis
9 Emission limits for interharmonics
10 Emission limits for telephone interference effects
Annexes
A Example of the "worst case impedance curve" approach
B Example of the manual calculation of the harmonic
impedance of a MV network at the PCC
C Example of particular rules for stage 1 limits in
MV networks
D General case of MV loads spread along the feeders:
sharing of emission
E Example of application of the approaches proposed for
assessing emission limits
F Examples in some typical HV cases
G List of principal symbol letters, subscripts and
symbols
H Bibliography
Defines principles for use as a basis for determination of the requirements for connection of large distorting loads (producing harmonics and/or interharmonics) to public power systems. The main concern is the provision of guidelines for engineering practices for ensuring adequate service quality for all connected customers.
