Webinar 1. "Improving quality and saving electric energy" (was held on May 17, 2016 at 11:00 Moscow time)

The quality of electric energy is one of the key indicators that determine the energy efficiency of power supply systems and largely influencing the useful life of the supplied loads. The divergence of quality parameters from the nominal values can be caused by both power supply quality provided by the energy supplier and the nature of consumers' electrical installations. Depending on the types of load in the systems and the quality of the electricity provided by the supplier, users are confronted with one of the following problems (or a combination thereof):

• uneven phase loading;

• low power coefficient;

• harmonic distortions;

• consequences of transients (starting currents and short-term voltage drop)

The problem of energy saving is topical at the present time, and taking into account the tendency of growth of tariffs for electricity will become increasingly important.

Currently, the market has a wide range of products designed to improve the quality of electricity, starting from the manufacturers of the "big four" - Eaton, GE, ABB, Siemens to the "revolutionary technologies" based on magnetic ceramic compositions, etc.

The main niche is occupied by various modifications of capacitor compensators, electric filters and so on. The most promising are technical devices that provide compensation within the framework of one block of the main negative factors listed above. Improving the quality of electric energy using this approach provides a number of advantages, including:

• significant reduction of losses in the system;

• increase of the system efficiency;

• electric energy saving;

• increase of the useful life of equipment;

• reduction of costs on maintenance and repairs of supplied loads

The main suppliers of solutions of this class: DMI Manufacturing, Inc., USA (Energy Bank Unit - EBU) and the domestic company "GREEN ENERGY" (Energy saving device - ESD). Due to the specificity of power supply systems, the DMI Manufacturing solution has not been widely used on the Russian market. UES allows to equalize the distribution of the load in phases, perform filtration of harmonic and improve the electromagnetic compatibility, increase the power factor, thereby increasing the percentage of the used power of the electricity mains, as well as protection from surges and currents, lightning protection. By improving the quality of electricity, it is ensured to save about 10-20%, and additional capacities are released. In addition to the direct economic effect of saving electricity, ESD contributes to longer service lives and lower maintenance costs for electronic equipment, electrical equipment (compressors, pumps, etc.).

Webinar 2. "Pilot project implementation procedure. Test Methodology "
(was held on May 24, 2016 at 11:00 Moscow time)

1. Selection of objects - connection points (2 - 4) Thye main grounding bus (MGB) / IDD (recommended option) or a TP can act as such. Installation closer to consumers is preferable: in this case we save on losses on the supply lines. Saving energy while using ESD Is achieved by improving the quality of electricity:
   • Improving the symmetry of the load currents in phases, compensation (partial) of phase imbalance;
   • increasing the power factor, reducing the load currents;
   • Reduction of the level of high-frequency harmonics, improvement of electromagnetic compatibility,
   • Smoothing of the shocks of load currents and short-term voltage drops.

The contribution of each of the components depends on their combination. Compensation of negative factors depends on the parameters of energy consumption. Thus, the efficiency of the UES is higher for dynamic heterogeneous loads (confirmed by practice), therefore, as a proposal, it is necessary to choose shield / TS supplying these kinds of loads.

Webinar 3. "Solution for the oil and gas sector"
(was held on June 7, 2016 at 11:00 Moscow Time)

Having considered the problems of power quality and how to eliminate them at the first webinars, we turn to specific industry solutions, the first of which is the use of energy saving devices (ESDs) at oil and gas facilities. At the webinar we will discuss solutions for various types of facilities (oil depots, gas stations / filling stations, etc.) and the specifics of working with various companies in the industry.

The results of using energy-saving devices at the sites of the leading Russian oil and gas companies (Rosneft, Gazpromneft) speak for themselves. The installation of the ESD at the Orelnefteprodukt - NK Rosneft (2 filling stations - 2013) allowed to increase the efficiency by 15-16% (in natural and value terms). The introduction of the ESD at Gazpromneft filling stations made it possible to get rid of problems with pumping and electronic equipment, due to the quality of supply voltages (from the traction substation of the Russian railways). 
In addition, we will definitely return to the topic of assessing the effectiveness of the ESD using standard accounting tools (counters), discussed in the previous webinar.

Objects that use energy-saving devices (ESD):

• oil and gas output;

• their production;

• transshipment (storage);

• sales - (filling station);

• office administrative premises.

Main problems in consumer networks:

• uneven phase loading;

• low power coefficient;

ESD of the Media model produced by CJSC "GREEN ENERGY" has been in operation since July 2015. During the operation, the parameters of the power consumption of the ESP TP-789 RU-0,4 kV were measured using the automatic information and power fiscal metering station of "MASH" JSC.

Increase of the useful usage and expenses for repairs and maintenance of equipment (ZhBK-40, Tomsk):
During the operation, the measurements were made using the company's own power metering units for long periods of time. By results, savings of ~ 10 - 12% were recorded. A decrease in the costs of repair and maintenance of the equipment feeding from this input - contactor contact and brush assembly of the electric motor.
