The paper justifies the suggestion of improving IDGC business assets volume calculation. Transition from “conventional units” to the index expressed in named units (kVA, MVA) through the installed capacity of electrical installations in distribution networks is presented. A methodology for calculating business assets volume in named units is given.

Overhead Transmission Lines

The paper presents some important issues related to implementation of specific innovative designs of multicircuit overhead transmission lines. The necessity of multicircuit overhead transmission lines implementation is confirmed by electrical grids and power supply systems operation under modern development conditions. Especially, such implementation is important to ensure electrical power supply of megacities.

Cable Lines

Mikhail Dmitriev, St. Petersburg Polytechnical University


In medium voltage networks there are many ways of grounding of a neutral. Among them are well-known insulated neutral, the neutral grounded through a reactor or resistor. The choice of optimal method of grounding depends upon many factors, including the characteristics used in network equipment. The article discusses the reasons for networks 6–35 kV containing cable lines with XLPE insulation to have resistive neutral grounding.

In recent years single-phase cables with XLPE insulation have been widely used in distribution networks. They consist of isolated conductors and screens, as well as external insulation. A large number of publications have been dedicated to justifying and choosing the methods of cable screens grounding. Those publications contain a lot of cumbersome arithmetic, complicated formulas and calculation programs for computers. When designing cable lines, the issues of cable screens grounding are central from the standpoint of power losses minimization (power losses impact on lines capacity significantly). Probably, this problem is presented as too complicated for 20 kV electrical networks. Relevant arguments are given in the paper.

The paper considers and compares the methods of screens connecting and grounding for phase-screened cables with XLPE insulation in 20 kV distribution networks. In addition to screens grounding methods are widely used in practice, the methods using discontinuities and joints of screens in the middle of the line, grounding through a resistor, grounding at one end of the line, and joint without grounding at the other end are considered. The impact of cable screens grounding methods on electrical safety, voltage on the screen in the steady state, advection of grounding device potential of main substation to distribution substations, electric power losses in the screens in the steady state, cable screens thermal resistance, voltage drop in cable lines and cable lines transmission capacity are analyzed.
