PD IEC TR 63191 discusses demand-side power quality management. The effective management of power quality on the demand side (power consumer) is an essential activity to ensure the proper operation of the electrical equipment operating on the consumer site. PD IEC TR 63191 specifies recommendations about power quality measurement and assessment within installations.
PD IEC TR 63191 outlines the various phases needed for the establishment of a demand side power quality measurement plan for buildings and industrial installations. A power quality measurement plan encompasses the following stages:
PD IEC TR 63191 will also help facility managers to tailor their measurement plan to the specific needs of the electrical system under their control. PD IEC TR 63191 addresses all the disturbances present in such networks.
Note: PD IEC TR 63191 does not cover the disturbances present in public electrical distribution networks (supply side) as they are governed by specific documents such as EN 50160 and IEC TS 62749.
PD IEC TR 63191 on demand side power quality management is useful for:
While the level of power quality present at the point of supply is generally monitored, and managed by the power provider (utility), the actual level of power disturbances present on the consumer site could be significantly worse and may negatively impact the operation of the electrical equipment. The interaction between these loads and the voltage supply is often the cause of degraded power quality on the demand side. One effective step in the prevention of the hindrances caused by power quality is the assessment of the level of power quality disturbance present on the demand side. However, proper measurements require adequate planning and understanding of the measurement systems and their results.
Disturbances in electrical energy can have an important impact on the equipment, processes, organization's activities and environment. Some electrical installations (industrial sites, data centres, hospitals, etc.) are particularly impacted by the poor quality of electrical energy. PD IEC TR 63191 provides guidance on how to establish, implement, exploit, maintain and improve a demand side power quality monitoring system. PD IEC TR 63191 will also facilitate the tailoring of power quality monitoring concepts to the specific site where they will be deployed. The quality of electrical energy has different origins, impacts and measurement indicators on the supply side and on the demand side, PD IEC TR 63191 presents an overview of the electrical network from generation (supply side) to consumer (demand side). Using PD IEC TR 63191:2018 you can specify recommendations about power quality management and assessment within installations.
