DESCRIPTION OF QUALITY CONTROL WITH THE CONSIDERATIONS OF SAIDI, SAIFI, CRP AND CPD INDICATORS FOR DISTRIBUTION SYSTEMS OPERATORS

The year 2015 was the last year in which the current model of regulating the five largest Distribution System Operators (OSDs) functioned. From 1 January 2016 on the basis of an agreement between the Energy Regulatory Office (ERO) and the DSO, a new model has been introduced. Updating the approach to setting the weighted average cost of capital, re-evaluating the efficiency of the company’s operating costs and balance sheet volume, as well as new elements of quality regulation.

The study presents a description of quality regulation including SAIDI, SAIFI, CRP and CPD for Distribution System Operators included in the new Regulatory Model for the years 2016 – 2020. The changes will affect the return on regulated revenues of electricity distribution companies. The consequence of failure to meet conditions and indicators according to the idea of ​​the new system will be to reduce the return on capital.

Abstract

Ground conductivity meters use electromagnetic fields for the mapping of geological variations, like the determination of water amount, depending on ground layers, which is important for the state analysis of embankments. The VLF band is contaminated by numerous natural and artificial electromagnetic interference signals. Prior to the determination of ground conductivity, the meter’s working frequency is not possible, due to the variable frequency of the interferences. Frequency management based on the analysis of the selected band using track-before-detect (TBD) algorithms, which allows dynamical frequency changes of the conductivity of the meter transmitting part, is proposed in the paper. Naive maximum value search, spatio-temporal TBD (ST-TBD), Viterbi TBD and a new algorithm that uses combined ST-TBD and Viterbi TBD are compared. Monte Carlo tests are provided for the numerical analysis of the properties for a single interference signal in the considered band, and a new approach based on combined ST-TBD and Viterbi algorithms shows the best performance. The considered algorithms process spectrogram data for the selected band, so DFT (Discrete Fourier Transform) could be applied for the computation of the spectrogram. Real–time properties, related to the latency, are discussed also, and it is shown that TBD algorithms are feasible for real applications.

Keywords: track-before-detect; ground conductivity meters; frequency management; radio interferences; frequency estimation; spectrogram; tracking; VLF

The concept of building the quality index of marine seismic surveys in order to improve their accuracy and effectiveness

The article presents the construction of a quantitative indicator of the quality of marine seismic surveys for a unit towing geophysical equipment in the form of a system of seismic cables with an installed assembly of geophones. The indicator of the quality of geophysical works is based on a mathematical model of positional deviation of a system of points of geophone cables in relation to the reference position. This indicator can be used in the implementation of seismic surveys and short-term forecasting of their course in terms of quality.

PROGRAMMES OF MANAGING DEMAND OF ELECTRICITY RECIPIENTS

PROGRAMMES OF MANAGING DEMAND OF ELECTRICITY RECIPIENTS

The article presents the current changes taking place in the Polish electric energy market. Today, the increase in importance of consumers in balancing energy demand is becoming more and more noticeable. Demand Side Management ( DSM) is a regular part of business management and a mechanism that has been known for years. Recently, a new term has gained importance – Demand Side Response (DSR), meaning the reaction of the demand side to signals coming from the market stimulated by the transmission system operator. DSR mechanisms require entities to voluntarily participate in the system of limiting power-receiving devices at the recommendation of the operator. Companies participating in the system will receive remuneration for this. The article brings closer the benefits of demand side management, sample DSR programmes and changes in the energy market caused by the implementation of DSR.

Magnetron sputtered TiN-Si3N4 films as a functional coatings

Magnetron sputtered amorphous Si3N4 films with included nanocrystals TiN are described in this paper. Target was prepared from powders mixture of 90 at.% Ti and10 at.% Al by hot pressing. Deposition was carried out with controlled gas flow of Ar and N2. The most important parameter for deposition such composite structure is a substrate  temperature not  higher then 0,2 reduced temperature. Deposition parameters and structural properties investigated by X-ray and TEM techniques are presented.  The picture of HRTEM  is presented in fig1. Heat reflection from a substrate with deposited TiN-Si3N4 film thickness about 100nm is noticeably higher.

publikacja2Fig.1. HRTEM for amorphous TiN-Si3N4 film.

Such coatings could be used for several applications which require high reflectance of IR. The adequate characteristics of reflectivity were measured. The temperature growth at the back side of substrate covered by TiN-Si3N4 coating was measured. The difference between covered and uncovered substrate are essential. It implies that  the professional cloths for firemen and other services could be covered by such coatings.
