Rapid voltage changes and their evaluation in comparison to IEC TR 61000-3-7 and EN 50160
Original language description
Voltage characteristics in the Czech Republic distribution networks are monitored on a long-term basis according to EN 50160, using permanently installed voltage quality analysers that comply with the requirements of IEC 61000-4-30 for class A instruments. Rapid voltage changes (RVCs) are monitored and evaluated, however, EN 50160 does not provide all necessary details to detect RVCs and distinguish them from voltage fluctuation. The definition of RVCs and the method for separating RVCs from voltage dips and swells are in IEC 61000-4-30, nevertheless the RVC setting is not unique. The magnitude and number of RVCs are detected and stored, but only if the voltage changes do not exceed the limits for voltage dips or swells. RVC, including compatibility and planning levels, are also addressed in IEC TR 61000-3-7, but individual emission limits are not specified. Moreover, according to clause 10.5 the worst case is assessed, i.e. the emission limit is applied for 100% quantile.
