What is PD IEC/TS 62257-9-2-Microgrids in decentralized rural electrification about?
The IEC 62257 series is a European standard that covers various aspects of recommendations for renewable energy and hybrid systems for rural electrification.
PD IEC/TS 62257-9-2 is the second part of the IEC 62257 series is a technical specification, that specifies the general requirements for the design and the implementation of microgrids used in decentralized rural electrification to ensure the safety of persons and property and their satisfactory operation according to the scheduled use.
PD IEC/TS 62257-9-2 applies to microgrids for decentralized rural electrification purposes.
The microgrids covered by this part of IEC 62257 are low voltage a.c., three-phase or singlephase, with rated capacity less than or equal to 100 kVA. They are powered by a single micropower plant and do not include voltage transformation. The rated capacity is at the electrical output of the micropower plant, that is, the upstream terminals of the main switch between the micropower plant and the microgrid.
Who is PD IEC/TS 62257-9-2-Microgrids in decentralized rural electrification for?
PD IEC/TS 62257-9-2 on renewable energy and hybrid systems for rural electrification is useful to:
- Rural electrification projects developers and manufacturers
- Rural electrification project implementers
- Rural electrification project contractors
- Rural electrification project supervisors
- Rural electrification installers
- Test in laboratories developing countries
Why should you use PD IEC/TS 62257-9-2-Microgrids in decentralized rural electrification?
Photovoltaic hybrid power systems are gaining attraction among rural electrification institutions as a way to reduce fuel price rises, produce lower operating costs, and provide improved service quality than traditional single-source generating systems.
PD IEC/TS 62257-9-2 improves the safety of persons, property and improves the efficiency of operation according to the scheduled use by providing general requirements for the design and the implementation of microgrids used in decentralized rural electrification.
PD IEC TS 62257-9-2 provides you guidance on renewable energy and hybrid systems for rural electrification products in terms of selecting the correct system for the right area, designing the system, and operating and maintaining the system.
Adopting guidance in PD IEC TS 62257-9-2 can be helpful for the safety, sustainability of systems and at the lowest life-cycle cost possible. PD IEC TS 62257-9-2 assist in promoting the use of renewable energies in rural electrification for developing countries.
What’s changed since the last update?
PD IEC/TS 62257-9-2:2016 supersedes DD IEC/TS 62257-9-2:2006 which is withdrawn. PD IEC/TS 62257-9-2:2016 includes some technical changes with respect to DD IEC/TS 62257-9-2:2006. These include:
- Changing the voltage range covered by the technical specification to a.c. nominal voltage below 1 000 V and d.c. nominal voltage below 1 500 V (introduction)
- Including 240 V 1-Ø/415 V 3-Ø, in the voltage levels (scope)
- Deleted microgrid and micropowerplants from terms and definitions
