Firstly, the application background of the system was introduced; Then, the design principles, system characteristics, architecture, and functions of the system were elaborated in detail; Summarized the important role of energy management system in dynamic monitoring of production energy consumption and improving energy efficiency of offshore oil platforms.
Keywords:Offshore oil fields; Energy management system; Dynamic monitoring of energy consumption; Energy efficiency
1. Introduction
Our country's economy continues to grow rapidly, but the accompanying side effects are also becoming increasingly apparent, with energy resources becoming increasingly scarce and environmental conditions deteriorating. To help high energy consuming enterprises achieve clean and efficient production, it is necessary to build energy consumption monitoring, management, and control systems, and use technological innovation to improve energy efficiency.
According to foreign statistical data, 8% of annual energy losses in industrial enterprises are caused by a lack of energy monitoring and maintenance plans, while the remaining 12% of energy losses are due to the absence of effective energy management and control systems. Developed enterprises in Europe and America widely adopt computer monitoring and control systems (such as DCS and SCADA) in their production processes, and attach great importance to online monitoring, analysis, and optimization systems for energy data.
With the help of modern computer technology, network communication technology, and distributed control technology, these enterprises have successfully established a comprehensive energy consumption monitoring and management system. This enables the dynamic process of energy consumption to be informatized, visualized, and controllable, enabling precise management, control, and optimization of the energy consumption structure, processes, and elements in the production process of enterprises. This comprehensive energy management approach not only helps reduce energy losses, but also significantly improves energy efficiency, bringing long-term economic and environmental benefits to enterprises.
The energy management system monitors the dynamic production energy consumption process of the entire enterprise online, collects a large amount of scattered energy consumption data such as electricity consumption during the production process, provides real-time and historical data analysis and comparison functions, and thus discovers problems in the production energy consumption process of the enterprise; By optimizing the operation mode and trajectory of energy consumption in enterprise production, and establishing an energy consumption evaluation and management system, the energy efficiency level of enterprises can be improved.
2、 Project Overview
The LF12-3 oilfield group development project is located in the South China Sea, including a multifunctional oil tanker (FPSO) that integrates production and storage, and a production platform LF12-3WHP connected by submarine cables. FPSO is equipped with 4 crude oil engines as power station platforms.
To meet long-term development needs, the newly built platform is equipped with a Power Energy Management System (PMS) and an Energy Consumption Management System (ECOMS). The difference in speed regulation and cliff jumping characteristics of generator sets makes it difficult to ensure stable operation of the power grid during grid connected operation. If the two are directly connected to the grid, it may cause fluctuations in the parameters of the power grid, thereby affecting the stability and reliability of the power grid. To ensure the safe and stable operation of the power grid, in-depth analysis and control of the speed and voltage regulation characteristics of these two types of generator sets are carried out to achieve collaborative work. Through the power supply energy management system and energy consumption management system of the power station, the power of the entire platform's power grid equipment is managed and dispatched uniformly, scientifically, and efficiently.
