• Equipment - There is more than only dip related parameters (depth and duration) - Wide range in device behaviour! • Processes - Definition of the PIT concept • All equipment is considered • Engineers from different disciplines join forces and learn from each other • Ongoing activities to validate the framework - Weaving loom manufacturer, steel cord production, …
Close collaboration between a range of specialists within an industrial facility is necessary for selecting an adequate level of equipment/process dip immunity.
This presentation describes the manner in which the implementation of a corporate approach from design to end-of-life cycle, combined with changes in the regulatory environment, effectively contributes to improving the safety and lifespan of prefabricated transformer substations. A remind of functional schema presented during the CIRED 2003 Conference will be done. It shows the main focus areas of...
Medium Voltage distribution power networks are dynamic systems in a constant state of flux. Load varies according to customer demand and regular patterns (daily and weekly) are often observed. These gradual variations are occasionally punctuated by step changes caused by network reconfigurations or underground cable faults. Together with environmental influences (weather, soil condition etc.), these...
The goal of grid operator Alliander is to obtain knowledge of the Power Quality in all parts of the network. Therefore continuous measurements must be performed on all MV busbars of HV/MV substations and on strategic points in the MV grid. From this data the quality in the LV network must be estimated. Incidental measurements in the LV network can help to obtain the experience needed for this estimation...
Independent generation has a long history in Portugal. Nevertheless the legal framework for licensing and interconnection was the same for a generator of 1kW and for a 50MW power station. In 2008, DL 363 entered in force and it was specifically aimed for microgeneration: (1) Easy internet registration; (2) Simplified licence; (3) Standard equipment; (4) Up to 3.68kW, initial tariff of 650€/MWh for...
Non-controlled DG has a limited potential The potential of controlled DG is bigger DG should be treated as an asset during network planning and design.
Our paper studies the long-term impact, in year 2020, of the development of Dispersed Generation on three expenditures of the French DNO ERDF: • Losses purchasing, • Draw off invoice paid to the transmission network operator RTE, • Investments costs in the primary substations.
• The problem of optimal operation of distribution systems is winning interest, as exploitation of distributed energy resources (DERs) is spreading. • New technologies and concepts for the operation of these networks are required in order to enable generators, storage units and loads working together in effective cooperation.
• The increase of DG in the Italian distribution networks has relevant impact on network planning and operation. • The trend imposes a deep thought on network planning and operational criteria. • Solutions for the current network in order to meet the highest technical standards in terms of quality of energy supply are already developed, while others are still in progress
A major part of decentralised production in the Netherlands consists of Combined Heat and Power-plants (CHP). Especially in the horticultural sector small CHP-plants with a maximum rating of 2,5 MW are applied. In these areas the CHP-plants are connected to the Medium voltage grid which leads to a high penetration level of CHP-plants. The Dutch law obliges grid operators to connect CHP-plants to the...
