6 Power Quality Waarom is dit belangrijk! Malfunction of computers and communication equipment Damage of home electronic equipment Tripping the drive systems of automated manufacturing processes Trans. 8% Voltage Swells 29% Interruptions 3% Misoperation of protective relays, saving your assets Generation of excessive losses and heating etc Voltage Sags 60% Economic losses EUR: about 300 Billion EUR/year worldwide!!!! Page 6

7 Power Quality: Niet alleen voor netbeheerders Trends Customer challenges Increasing energy costs Increasing energy costs: Drive variable operating costs because 50 60% of these are energy costs. CO 2 reduction CO 2 reduction: A typical refinery needs carbon certificates for ~170 kg CO 2 / gross ton of production. Grid capacity / Reliable energy supply Energy outages: 1 hour outage = 1.000,000 revenue loss for refinery operator. Minimizing of production costs Source: Mineralölwirtschaftsverband MWV Page 7

8 Huidige status Nederland - Energie Nederland: - Richtlijnen voor toelaatbare harmonische stromen - Netbeheer Nederland: - PQM project (voor TSO en DSO) - ACM: - Netcode - ACM publiceert Factsheets Kwaliteit Regionale Netbeheerders - Meetrapport uitgevoerd door Laborelec (2012) - Commissies, verenigingen, gebruikers en netbeheerders: Hoe om te gaan met dips en transienten Transparantie op het overdrachtspunt? Waarom niet gezamenlijk meten en gegevens delen? Page 8

9 Spanningskwaliteit vanuit optiek van de ACM Spanningskwaliteit als een belangrijk aspect in het waarborgen van de betrouwbaarheid van de elektriciteitsnetten (wettelijke taak, art. 16, eerste lid, onderdeel b van de Elektriciteitswet) Verantwoordelijkheid van netbeheerders en afnemers Is het huidige niveau van spanningskwaliteit goed? Gewenste ontwikkelingen: Monitoring Registratie Transparantie Aansluiting bij EU ontwikkelingen Page 9

10 ACM aanbevelingen n.a.v. onderzoek 1. Normering meer normen: - Spanningsdips in MS netten 2. Betrouwbaar beeld over spanningskwaliteit meer metingen: Alle aansluitingen op EHS en HS netten voorzien met continue metingen Alle (E)HS/MS stations voorzien met continue metingen voor spanningsdips Steekproef in MS en LS netten vergroten van 60 naar 250 weekmetingen 3. Transparantie meer transparantie: Verschillende verbeteringen in de rapportages Openbare rapportage tool voor het brede publiek Uniforme behandeling en registratie van klachten 4. Impact van speciale projecten meer duidelijkheid: Impact van de speciale projecten inzichtelijk maken voor het brede publiek Indien nodig metingen op speciale projecten alsnog plaatsen Page 10
