PD IEC/TS 62257-4:2015

What is PD IEC/TS 62257-4-Renewable energy and hybrid systems for 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 62257-4 is the fourth part of the series that provides a method for describing the results to be achieved by the electrification system independently of the technical solutions that could be implemented.

PD IEC/TS 62257-4 provides a method to assist project contractors and project developers to select and design the electrification system for isolated sites while matching the identified needs, such as those described in IEC TS 62257-2. IEC TS 62257-2 assesses the needs of the users and the different power system architectures which can be used for meeting these needs. In relation to the needs of the different participants to the project, functional requirements that shall be achieved by the production and distribution subsystems are listed.

Who is PD IEC/TS 62257-4- Renewable energy and hybrid systems for rural electrification for?

PD IEC/TS 62257-4 on renewable energy and hybrid systems for rural electrification is useful 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 62257-4-Renewable energy and hybrid systems for 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 62257-4 technical specification specifies a method for describing the results to be achieved by the electrification system independently of the technical solutions that could be implemented.

PD IEC/TS 62257-4 helps you to allow and facilitate the management of the micro-power plant and the maintenance of the whole electrification system, some information is collected and monitored.

PD IEC/TS 62257-4 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 the best industry guidance in PD IEC/TS 62257-4 can be helpful for the safety, sustainability of systems and at the lowest life-cycle cost possible. PD IEC/TS 62257-4 assist in promoting the use of renewable energies in rural electrification for developing countries.

What’s changed since the last update?

PD IEC/TS 62257-4:2015 supersedes DD IEC/TS 62257-4:2005 which is withdrawn.

• Redefine the maximum AC voltage from 500 V to 1 000 V, the maximum DC voltage from 750 V to 1 500 V
• Removal of the limitation of 100 kVA system size. Hence the removal of the word “small” in the title and related references in this technical specification.
