Guideline for planning of HVDC systems - HVDC systems with line-commutated converters not-for-sale Macroinvertebrates are important in water1 Scope This document provides guidelines for the selection of a high voltage directive current (HVDC) system with line commutated converters (LCC), hereafter referred to as HVDC system, for the purposes of HVDC system planning. It covers the guidelines on the requirements for integrating HVDC systems in AC power networks, selection of rated voltage and power, overloads, circuit configuration, expandability, comparison of technical, economic,
