The realization of the present invention, substantially increases the oil exploitation offshore platform management level to the energy, and reason is as follows:
One, basis energy consumption data is integrated
Doing energy consumption control system, data are bases, leave energy consumption data, and the management of all, control, analysis, improvement are all " water of unrooted, without this originally ", and data are the foundation of energy consumption control system, carry out system, it is necessary to lay a solid foundation.
1, for " data and focus on " problem comprehensively
The most control data that produce of offshore platform are deposited in DCS production control system, and electric energy management data are deposited in EMS electric energy management system and DMS power management system, and other data are scattered in other automated systems.
Present system provides abundant automation interface and customized development, for producer of each automatization and electric meter, adopts OPC and the Modbus communication interface of standard, directly obtains data, and unified storage enters data base;
2, for " promptnesses of data " problem
Having part data acquisition manual metering, meter reading data is typically stored in the xls form of machine, very regular.For manual meter reading data, develop the module of special customization, obtain data storage from the Data Position that xls form is fixing and enter data base, it is ensured that the promptness of data.
Promptness is relative, for manual meter reading data, it is desirable to can not require consistent with the system having communication interface and smart machine, but can ensure that artificial some typing xls form and data according to the rules immediately enter energy management system and participate in analyzing.
3, for " data integrity degree statistical analysis " problem
Data integrity directly affects the result of statistical analysis, and the result of analysis can affect artificial judgement.Energy management and control is an overall analysis system, it is first necessary to have all multi-energy data about metering as most basic foundation, with other life, creation data, and other manual meter reading datas are as some assistant analysis, the direct or indirect impact on multi-energy data.
For all of statistical analysis data out, system can provide certain advisory opinion according to the data integrity degree analysis participating in statistics and analysis, actual analysis result needs 1000 energy resource collecting points, what actual participation was analyzed is likely to only 998, the integrity degree of data should be provided to analysis personnel when obtaining final data statistics simultaneously, what such analysis personnel can rule of thumb judge data may finally utilization rate, statistics and analysis without data integrity degree, the validity of the statistical data of the energy management and control that analysis personnel and management personnel get is difficult to ensure that.
Two, multi-energy data is concentrated statistics, is analyzed and show

In details, the statistical analysis of comprehensive energy efficiency index, statistical universe and each land regions are in indexs such as the day, week, month, year specified and the power consumptions of the unit are in the self-defined period, per capita power consumption, the power consumption of working unit time;In the day, week, month, year specified and the relative analysis that in the self-defined period, different factory areas, area meterin object are carried out unit are power consumption, per capita power consumption and working time capability of energy dissipation result;Carry out overall and equipment subsystem of respectively itemizing, production platform, power distribution station area meterin object and amount to the statistical analysis of standard coal and CO2 emissions at the day, week, month, year specified and the classification energy in the self-defined period.
3, the operational diagnostics analysis of distribution system is divided into safe distribution of electric power diagnosis and power consumption efficiency diagnosis.Safe distribution of electric power diagnoses by monitoring the distribution key parameters such as the voltage of distribution system, electric current, power, power factor (PF), non-equilibrium among three phase voltages in real time; automatically acousto-optic animation and event alarm is carried out when abnormal parameters occurring or transfiniting; notice operator and management director carry out intervening control timely; as monitor power factor (PF) too low time take treatment measures in time, it is ensured that while safety utilization of electric power save energy operating cost;Power consumption efficiency diagnosis judges, mainly by energy resource consumption distribution and the Integrated Energy index of statistics different periods, the efficiency that system is current.
Three, energy source optimization management
1, the management of energy source optimization, is first pass through table meter real-time exhibition classification energy service condition, it is provided that with energy real-time tendency curve.By in system operation to can the monitoring in real time and the parameter closely-related with energy consumption such as bonding apparatus running status, technological process of situation, energy consumption is carried out rational management and control and early warning, finds and correct the energy abnormal problem existed in operation in time.
2, strengthening administration of energy conservation, refers mainly to based on management energy saving model, realizes automatization entirely in real time with monitoring and with controlling, reducing unnecessary energy waste with technological means;And by the comprehensive relative analysis to energy consumption data, grasp energy distribution in time, process energy consumption at any time abnormal.Can be combined with administrative means and energy-conservation performance appraisal target and check-up system are set, cultivate everybody sense of participation, set up rewards and punishments in conjunction with system, promote the real effectively execution that offshore platform is energy-saving and cost-reducing.
3, in energy conservation object, comprehensive carry out maritime terminal, each energy consumption data of platform is analyzed, by energy source type, loadtype, region, according to timing separation, on time, sky, the moon, year etc. are to data carrying out comprehensive relative analysis, the concrete Expenditure Levels of the accurate perception energy, Comparison of Energy Consumption result can be used for performing energy-conservation performance appraisal and the correction of offshore platform energy conservation object.
4, in optimum management, day-to-day operation optimization and real-time dynamic monitoring to crucial energy consumption equipment, monitoring and management to power supply-distribution system, monitoring and warning function in real time are provided, operational monitoring and regular maintenance optimum management can be carried out by equipment to each, and energy source optimization operation reserve and decision support suggestion are provided.
