Analysis of the structure and energy parameters of the electrical complex (EC) of gas complex №1 «Gazprom dobycha Yamburg» LLC

Abstract

THE PURPOSE. Consider the structure of the centralized and autonomous power supply system for gas field (GF) №1 of «Gazprom dobycha Yamburg» LLC. Perform the calculation of the main energy indicators (consumed active, reactive and apparent power, power factors, reactive power factors) for each section of busbars (SB) of complete transformer substations (CTS) according to wattmetrograms taken by electromechanical meters on the linear cells of closed switchgear (CS) during a calendar year. Calculate the peak current of a group of electric receivers (ER) for each CS CTS. To analyze the features of the functioning and the load factor of the autonomous power supply system from diesel power plants (DPP) according to the schemes: “one generator - a separate group of electrical consumers” (EС-1) and a single generation center with a cascade (ring) switching circuit (EС-2). Compare the annual fuel consumption of diesel power plants with EС-1 and EС-2 by monthly load factors.METHODS. When solving the problem, an approximate method was used to determine the energy indicators of electrical loads at each CS CTS and the load factors of DPP according to the readings of active power (wattmetrograms) for the period under consideration.RESULTS. The article describes the relevance of the topic, considers the features of the construction and functioning of the EC for a centralized and autonomous power supply system. An approximate calculation of the energy parameters at the each CTS SB of the integrated gas treatment plant (IGTP) and the booster compressor station (BCS) was made based on the readings of the active power consumed during the period under consideration. This article discusses the fuel and energy characteristics and features of the functioning of DPP. The monthly and annual weighted average load factors were calculated and the peak currents of the ER group were determined for each DPP. The calculation of the annual fuel consumption of DPP with EС-1 and EС-2 has been made according to monthly load factors.CONCLUSION. As a result of the analysis of the structure and energy characteristics, the features of the functioning of the centralized and autonomous power supply system were revealed, which determine the range of problems and shortcomings that require further research and study, with the subsequent development of a set of measures to improve the energy efficiency of the EC.
