Summary This standard applies to include power converter equipment, control equipment and motors AC variable speed electrical power drive systems. But does not include railway and electric vehicle traction drive transmission. This section applies to converter voltage (line voltage) range of AC 1kV ~ 35kV, the input side of the frequency of 50Hz or 60Hz, 600Hz frequency to a load side of the electrical transmission system. (See Figure 1) to the voltage of 15kV or more requirements of the system is not included, by the manufacturer and the system provider agreed upon. For voltages above 1kV, using low-voltage current transformer (less than 1kV) input transformer connected to the buck and/or boost the output transformer electric drive, GB/T 12668. 2-2002 apply. GB 12668. 3-2003 given electromagnetic compatibility (EMC) requirements. IEC 61800-5 gives the right voltage above 1kV electrical transmission system specific security requirements. This section presents the characteristics of inverter, converter topologies and AC electrical drive system with the entire relationship. It also provides information on ratings, the normal conditions of use, overload, surge capacity, stability, protection, AC power ground topology and testing and other performance requirements. In addition, this section also gives control scheme such as torsional vibration analysis application guide and give information about grounding and electric drive components integrated the recommended method.
