What is PD IEC/TS 62257-9-3-Interface for microgrid 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 62257-9-3 is the third part of the IEC 62257 series is a technical specification, that specifies the general requirements for the design and the implementation of the interface equipment within the user’s installation which connects to a microgrid or the generating part of a standalone system.
PD IEC/TS 62257-9-3 applies to simplified user interfaces (distribution board) in electrical installations with a maximum power of 500 VA in Decentralized Rural Electrification Systems (DRESs).
PD IEC/TS 62257-9-3 applies to interface equipment within the user’s installation, and which connects the user's installation to:
- 240 V or 230 V or 220 V or 120 V a.c. microgrid
- The generating part – a.c. or d.c. – of a standalone installation
Who is PD IEC/TS 62257-9-3-Interface for microgrid for?
- 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 62257-9-3-Interface for microgrid?
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 62257-9-3 specifies the general requirements for the design and deployment of interface equipment within the user's installation that links to a microgrid or the generating component of a freestanding system.
PD IEC TS 62257-9-3 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 62257-9-3 can be helpful for the safety, sustainability of systems and at the lowest life-cycle cost possible. PD IEC TS 62257-9-3 assist in promoting the use of renewable energies in rural electrification for developing countries.
What’s changed since the last update?
PD IEC/TS 62257-9-3 supersedes DD IEC/TS 62257-9-3:2006 which is withdrawn. PD IEC/TS 62257-9-3 includes some technical changes with respect to DD IEC/TS 62257-9-3:2006. 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)
- Deleted below 100 kVA from upper limit
- Including 240 V and 220 V 1-Ø in the voltage levels (scope)
- Deleted the terms microgrid and micropowerplants from terms and definitions.
- Stated the requirement for segregation between a.c. and d.c circuits in housing (6.5)
