37、py: sheffieldun sheffieldun, na, Thu Nov 09 14:36:02 GMT+00:00 2006, Uncontrolled Copy, (c) BSI INTRODUCTION The standard contains some requirements for a safe operation of wind turbine generator systems falling in the scope of Article 118a of the EC Treaty. Users of this Standard should, with the r
38、espect to these requirements, be aware that standards have no formal legal relationship with Directives which may have been made under Article 118a of the Treaty. In addition, national legislation in the Member states may contain more stringent requirements than the minimum requirements of a Directi
39、ve based on Article 118a. Information on the relationship between the national legislation implementing Directives based on Article 118a and this Standard may be given in a national foreword of the national standard implementing this Standard. Any of the requirements of this standard may be waived i
40、f it can be suitably demonstrated that the safety of the system is not compromised. Nevertheless this waiver does not apply to clause 6. Compliance with this standard does not relieve any person, organization, or corporation from the responsibility of observing other applicable regulations. Page 6 E

42、 specifies requirements for the safety of Wind Turbine Generator Systems (WTGS), including design, installation, maintenance, and operation under specified environmental conditions. Its purpose is to provide the appropriate level of protection against damage from all hazards from these systems durin
43、g their planned lifetime. This standard is concerned with all subsystems of WTGS such as control and protection mechanisms, internal electrical systems, mechanical systems, support structures and the electrical interconnection equipment. This standard applies to WTGS with a swept area equal to or la
44、rger than 40 m2. This standard should be used together with the appropriate IEC/ISO standards identified in clause 2. The standard contains requirements which directly address the operator of wind turbine generator systems. These requirements for a safe operation, however, constitute recommendations
45、 for the manufacturer, designed to support him in drafting the operation instruction handbook. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 61400. At the time of publication, the editions
46、indicated were valid. All normative documents are subject to revision, and parties to agreements based on this part of IEC 61400 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
