静止无功补偿器(SVC).晶闸管阀的试验

[中文适用范围]： 本国际标准定义了晶闸管控制电抗器 (TCR)、晶闸管开关电抗器 (TSR) 和晶闸管开关电容器 (TSC) 中使用的晶闸管阀的型式@生产和可选测试，这些晶闸管阀构成电力系统应用的静态无功补偿器 (SVC) 的一部分。该标准的要求既适用于单阀装置（一相），也适用于多阀装置（多相）。第 4 章至第 7 章详细介绍了型式试验，即为验证阀门设计是否满足规定的要求而进行的试验。第 8 条涵盖了生产测试@，即为验证制造是否正确而进行的测试。第 9 条和第 10 条详细说明了可选测试，即型式和生产测试之外的测试。 [外文原描述]： IEC 61954:2011 defines type, production and optional tests on thyristor valves used in thyristor controlled reactors (TCR), thyristor switched reactors (TSR) and thyristor switched capacitors (TSC) forming part of static VAR compensators (SVC) for power system applications. The requirements of the standard apply both to single valve units (one phase) and to multiple valve units (several phases). This edition includes the following significant technical changes with respect to the previous edition: a) Definitions of terms "thyristor level", "valve section", "valve base electronics" and "redundant thyristor levels" have been changed for clarification; b) Conditions of testing thyristor valve sections instead of a complete thyristor valve have been defined; c) The requirement has been added that if, following a type test, one thyristor level has become short-circuited, then the failed level shall be restored and this type test repeated; d) The time period of increasing the initial test voltage from 50 % to 100 % during type a.c. dielectric tests on TSC, TCR or TSR valves has been set equal to approximately 10 s; e) The duration of test voltage Uts2 during type a.c.-d.c. dielectric tests between TSC valve terminals and earth as well as the duration of test voltage Utvv2 during dielectric tests between TSC valves (for MVU only) has been changed from 30 min to 3 h; f) The reference on the number of pulses per minute of the periodic partial discharge recorded during a.c.-d.c. dielectric tests on TSC valves and exceeding the permissible level has been deleted.
