Main factors to be considered (see Chapter 8); --- Increase the converter station control and protection model to study the factors that need to be considered before the retarding wave (see 10.3.5); --- Re-integration of the contents of the creepage distance, and added the relevant description (see Chapter 11, the.2007 edition of 7.6,8.1,8.2,8.3) --- Re-integration of the information on the air gap of the converter station with the addition of the relevant description (see Chapter 12, 7.7, 8.4 of the.2007 edition); --- Increased DC line and ground line over-voltage protection and insulation coordination (see Chapter 13). This section uses the redrafted law to amend the use of IEC 60071-5.2014 "insulation coordination with Part 5. HVDC converter insulation with Combined procedures. " This part of the structure compared with IEC 60071-5.2014 compared to more adjustment, Appendix A lists this section and IEC 60071-5. 2014 reg number reference table. This section there are technical differences compared with IEC 60071-5.2014, the provisions of these differences have been passed in the outer margin of its margin The vertical single line (|) of the position is marked. This part of IEC 60071-5.2014 technical differences and the reasons are as follows. --- On the normative references, this section made a technical difference with the adjustment to adapt to China's technical conditions, adjust the situation Concentration reflected in the second chapter "Normative references", the specific adjustments are as follows. ● increase the reference GB/T 22389, GB /Z 24842-2009, GB/T 25083-2010, GB/T 50064-2014, DL/T 5224-2014, IEC 60099-9; ● Replacing IEC 60071-1.2006 with GB 311.1-2012 modified to adopt international standards; ● GB/T 311.2-2013 modified to adopt international standards instead of IEC 60071-2.1996; ● Replacing IEC 60099-4.2006 with GB 11032-2010 modified to adopt international standards; ● Equivalent to the international standard GB/T 13498 instead of IEC 60633.1998; ● Replaced GB/T 16927.1-2011 replacing IEC 60060-1.2010 with international standard; ● with the amendment to adopt international standards GB/T 26218.1-2010, GB/T 26218.2-2010, GB/T 26218.3- 2011 instead of IEC /T S60815-1.2008, IEC /T S60815-2.2008, IEC /T S60815-3.2008. --- Added the term "performance indicators" (see 3.22). --- Figure 1 single tuned filter configuration does not meet the practical application of the domestic situation, it changed to the actual application of engineering in China single Very double 12-pulse converter unit series structure arrester layout (see Chapter 5 Figure 1). --- Increased AC and DC system resonant overvoltage content (see 7.4.4, 7.4.5). --- Increasing arrester DC reference voltage, charge rate and DC bias voltage selection principles and methods (see 8.2.1, 8.2.2). --- Increasing the double 12 converter converter station smoothing reactor arrester parameters of the layout (see 8.3.7,8.3.8,8.3.9). --- Added neutral bus high energy arrester arrangement (see 8.3.11). --- Increase the converter valve side winding SIWV/LIWV ratio (see Chapter 9). --- Increased converter station control and protection model to study the factors that need to be considered before the retarding wave (see Chapter 10). --- Increased DC line and ground line over-voltage protection and insulation coordination (see Chapter 13).

1 Scope

1.1 Overview This part of "Insulation coordination" gives the insulation coordination procedures for high voltage direct current (HVDC) converter stations without standard insulation levels Guidelines. This section only applies to high-voltage AC power system in the high-voltage DC part, but not for industrial use commutation equipment. Given Principles and rules apply only to the purpose of insulation. This section does not involve the requirements of personal safety. 1.2 Background Description High-voltage DC converter station converter thyristor valve series or parallel composition, and the commutation process using a unique control and protection, Compared with the AC substation, therefore, the overvoltage protection of the equipment made special requirements. This section gives the withstand voltage, DC Voltage, harmonic voltage and surge voltage converter station equipment over voltage and insulation with the program. Proposed series or parallel arrester protection water Flat, optimize the configuration of the arrester program. Examples of insulation coordination for conventional and back-to-back DC converter stations are given (see Appendix B, Appendix C). This section describes the converter substation and conventional substation in the insulation with the basic principles and design goals difference. This section only relates to the current gapless metal oxide surge arresters for overvoltage protection of HVDC converter stations. Arrester base is given This characteristic, requirement and the calculation process of the maximum over-voltage in operation; put forward a typical arrester configuration scheme, arrester stress and determine the Method of stress. This section includes the converter station exchange field (excluding AC lines) and DC field equipment insulation coordination. Due to line and cable commutation Station equipment with the impact of insulation, it is also included. Although this section is used for ordinary HVDC system (commutating voltage from the AC filter bus), but the main principle of insulation fit For use in Appendix C, Capacitor Commutation (CCC) Converters and Controllable Series Compensators (CSCC), and Appendix E for some specific converter configurations. This section discusses the insulation coordination of the Line Commutated Converter (LCC). This section does not include flexible DC voltage source converter (VSC).
