Incorporating corrigendum December 2010:2010+A1 Foreword This European Standard was prepared by Working Group 1, Physical characteristics of electrical energy, of the Technical Committee CENELEC TC 8X, System aspects of electrical energy supply. It was submitted t

12、o the formal vote and was approved by CENELEC as EN 50160 on 2010-03-01. This document is the result of an intensive cooperation between CENELEC and CEER, with involvement of CEER experts in TC 8X WG1 as well as in related Task Forces. This document supersedes EN 50160:2007. Attention is drawn to th

13、e possibility that some of the elements of this document may be the subject of patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent rights. The following dates were fixed: latest date by which the EN has to be implemented at national level by publicatio

14、n of an identical national standard or by endorsement (dop) 2011-03-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2013-03-01 The main differences from EN 50160:2007 are: new organization of the document by grouping clauses related to events and con

15、tinuous phenomena; modification of some definitions and completion by some new definitions; new Clause 6 relevant to voltage characteristics in high voltage networks. This work has been deemed so important, that before submission for vote, a CENELEC enquiry has been made, where NCs had the opportuni

16、ty to respond to the most essential questions resulting from the WG discussions. This enquiry resulted in an extensive number of valuable comments, which have been carefully examined for possible consideration either for the voting draft in particular or for further work within WG1 on some main issu

17、es. Following that, the draft has been revised in depth, considering in particular the comments received on: the subclauses relevant to supply voltage changes, where a new formulation (capable of encompassing the needs expressed by the vast majority of the NCs) has been introduced, the new Clause 6,

18、 relevant to voltage characteristics in high voltage networks, where limits for harmonics and unbalance have been changed into indicative values, as new measurement surveys are taking place in several European countries, and it has been recognized as appropriate to wait for the relevant results befo

19、re considering the setting of limits. Foreword to amendment A1 This document (EN 50160:2010/A1:2015) has been prepared by CLC/TC 8X “System aspects of electrical energy supply“.

22、ence of the CEN-CENELEC national member. This European Standard does not fall under any Directive of the EU. In the relevant CEN-CENELEC countries, these A-deviations are valid instead of the provisions of the European Standard until they have been removed. Clause Deviation Norway The Norwegian Regu

23、lation No 1557 of 30 November 2004 on quality of supply in the Norwegian power system shall contribute to ensure a satisfactory quality of supply in the Norwegian power system and a social rational operation, expansion and development of the power system. This includes taking into account public and

24、 private interests affected. All deviations below are given according to this regulation and the requirements are stricter than the current edition of the EN 50160. The various parties responsibility for rectifying the situation when problems occur may differ from case to case. This regulation appli

25、es to those who wholly or partially own, operate or use electrical installations or electrical equipment that are connected within the Norwegian power system, and who pursuant to the Energy Act is designated transmission system operator. This regulation does not apply in Norwegian territorial waters

26、, to direct-current voltage installations or to railway installations in Norway with a frequency of 16 2/3 Hz. 3.17 The following definition applies for rapid voltage changes: Rapid voltage changes: A change of the voltage rms value within 10 % of the agreed voltage level and which occur more rapid

27、than 0,5 % of the agreed voltage level per second. Rapid voltage changes are expressed as the steady state and the maximum voltage change given respectively by: %100% =agreedesteadystatesteadystatUUU%100%maxmax=agreedUUU, where Usteadystateis the steady state voltage change due to a voltage change c

28、haracteristic, Umaxis the maximum voltage difference during a voltage change characteristic, and Uagreedis the agreed voltage level (i.e. the nominal or the declared). A voltage change characteristic is the time function of the rms voltage change evaluated as a single value for each successive half

29、period between zero-crossings of the source voltage between time intervals in which the voltage is in a steady state condition for at least 1 second. The voltage is in a steady state condition when the rms value is in between 0,5 % of the agreed voltage rms level. BS EN 50160:2010+A1:2015 EN 50160:2

40、This European Standard defines, describes and specifies the main characteristics of the voltage at a network users supply terminals in public low voltage, medium and high voltage AC electricity networks under normal operating conditions. This standard describes the limits or values within which the

41、voltage characteristics can be expected to remain at any supply terminal in public European electricity networks and does not describe the average situation usually experienced by an individual network user. NOTE 1 For the definitions of low, medium and high voltage see 3 (Definitions). This Europea

42、n Standard does not apply under abnormal operating conditions, including the following: a) a temporary supply arrangement to keep network users supplied during conditions arising as a result of a fault, maintenance and construction work, or to minimize the extent and duration of a loss of supply; b)

43、 in the case of non-compliance of a network users installation or equipment with the relevant standards or with the technical requirements for connection, established either by the public authorities or the network operator, including the limits for the emission of conducted disturbances; NOTE 2 A n

44、etwork users installation may include load and generation. c) in exceptional situations, in particular, 1) exceptional weather conditions and other natural disasters; 2) third party interference; 3) acts by public authorities; 4) industrial actions (subject to legal requirements); 5) force majeure;

45、6) power shortages resulting from external events. The voltage characteristics given in this standard are not intended to be used as electromagnetic compatibility (EMC) levels or user emission limits for conducted disturbances in public electricity networks. The voltage characteristics given in this

46、 standard are not intended to be used to specify requirements in equipment product standards and in installation standards. NOTE 3 The performance of equipment might be impaired if it is subjected to supply conditions which are not specified in the equipment product standard. This standard may be su

47、perseded in total or in part by the terms of a contract between the individual network user and the network operator. NOTE 4 The sharing of complaint management and problem mitigation costs between the involved parties is outside the scope of EN 50160. Measurement methods to be applied in this stand

48、ard are described in EN 61000-4-30. 1.2 Object The object of this European Standard is to define, describe and specify the characteristics of the supply voltage concerning: a) frequency; b) magnitude; c) waveform; d) symmetry of the line voltages.

49、 These characteristics are subject to variations during the normal operation of a supply system due to changes of load, disturbances generated by certain equipment and the occurrence of faults which are mainly caused by external events. The characteristics vary in a manner which is random in time, with reference to any specific supply terminal, and random in location, with reference to any given instant of time. Because of these variations, the values given in thi
