Abstract

This chapter provides a technical description of the Static Var Compensators (SVC) used in electrical power systems. It highlights the technological evolution from the 1980s, when the first SVCs were installed in Brazil, until the later SVCs installed in Brazil. Aspects of the control systems used in the two groups of SVCs are described, highlighting the advantages of the use of adaptive control systems in the later generation SVCs. The chapter also describes an innovative solution that uses a series reactor to reduce the harmonic filtering requirements and to avoid resonances with the power grid. This equipment is in operation in Brazilian Electric Power Grid since December 2016. The chapter also provides details of a control scheme used to coordinate the operation of two SVCs installed electrically close in the Brazilian Electric Power Grid.

Notes

  1. 1.

    αc is the TCR firing angle that produces TCR admittance equal in magnitude to the TSC value (B [TCR (αc)] = B(TSC).

  2. 2.

    Note that in the IEEE standard C57.110 for regular power transformers, the eddy current and stray losses are given the same weight.

  3. 3.

    See, for example, data sheet for a device 5STP 42 U6500. https://library.e.abb.com/public/c92a9062c3392b1f83257c63004dbb1d/5STP%2042U6500_5SYA1043-07%20Mar%2014.pdf, accessed November 11, 2018.
