BS PD IEC/TS 62257-4:2015

BS PD IEC/TS 62257-4:2015 provides a method for describing the results to be achieved by theelectrification system independently of the technical solutions that could be implemented.The purpose of this part of IEC 62257 is to provide a method to assist project contractors andproject developers to select and design the electrification system for isolated sites whilematching the identified needs, such as those described in IEC TS 62257-2. IEC TS 62257-2assesses the needs of the users and the different power system architectures which can beused for meeting these needs. In relation to the needs of the different participants to theproject, functional requirements that shall be achieved by the production and distributionsubsystems are listed.In Clause 5, energy management rules to be considered are described. These are key issuesas they have a great influence on the sizing of the electrification system.In Clause 6, the informations provided by the system sizing process to allow the participantsto select the equipment or component able to fulfil the functional requirements are listed.To allow and facilitate the management of the micro-power plant and the maintenance of thewhole electrification system, some information is collected and monitored.Clause 7 is dedicated to defining the parameters and specifying rules for data acquisition.Cross References:IEC/TS 62257-2:2015IEC/TS 62257-3:2015
