Introduction

Summarize the energy sector economy and the problems of the power companies in the market. Characterize the technical and economic indicators of power companies.

Show the organizational chart of the functioning of the electricity market in Kazakhstan. Identify the key problems in the organization and functioning of the electricity market.

The variants for data students to carry out CGW select from Tables 1, 2, 3 of Annex A on the last two digits of Gradebook.

2. Calculating and graphic works №1. Determination of the annual electricity demand, building the load graphs and selection of equipment

2.1 Determination of the annual electricity demand

Total annual demand for electricity in the planning year in the established power system is based on:

- Actual electricity system subscribers for the year;

- The proportion of consumers in the annual consumption of electric power;

- Annual growth of electricity power system subscribers;

- Electricity losses in networks.

W = W_net + W_{losses ,} МW·h/year, (1)

where W_net, - the planned net supply of electric energy by-industries

W_losses – electricity losses in networks.

Formula (1) can therefore be written as:

W = W_ind+ W_hous + W_agr + W_tran + W_losses, (2)

where W_ind – industries;

W_hous – household consumers;

W_agr – agricultural production;

W_tran – electrified transport_.

The necessary input data for determining the efficiency of the planned vacation in electricity production is given in Annex A.
