in Energy Management Regulation.Routine parameters and consumption record(by operation engineer).Weekly statistics and analysis(by PM engineer)Abnormal data will be fed back to relevant personnel to find the reason.Statistics information is provided to related departments regularly.Monitoring if energy charges are consistent with actual consumption.,Oct 12,2007,18,Statistics&analysis of energy consumption,Original data recordRecord readings of power supply,water supply,natural gas supply,nitrogen flow,hydrogen flow at 8 oclock on every Sunday.These records are to be used as original data of energy statistics&analysis.Calculate weekly consumption quantities and costs.Calculate energy costs per k productsConfirm if the data is abnormal according to the comparison with historical data.Use the tools such as line chart,column chart,pie chart to compare&analyze energy costs.Find the reason of abnormal data and eliminate the problems.,Oct 12,2007,19,Energy statistics process,Oct

12,2007,24,Advantage and limitation of trend diagrams,AdvantageReflect the trend of energy consumptionsDetect abnormal data according to comparison between total consumption and consumption per k products.Judge whether the reason is from supply lines and user equipment according to variation trends of consumption.LimitationNatural gas consumption only correlates with outdoor temperature instead of product output.So when the efficiency drops,abnormal data cannot be found on the trend diagram.Abnormal data will be detected when water consumption rises in summer.But it is hard to judge if the data is reasonable.,Oct 12,2007,25,Monthly cost analysis,Purpose of cost comparison column chart Reflect the relative scale of each cost accounts in total cost.Show the variation trend of each cost.,Oct 12,2007,26,The purpose of pie chart：Directly shows relative ratio of each costs.,Oct 12,2007,27,Pie chart of annual average cost per k products provides finance detailed information of cost analysis.,Oct 12,2007,28,Line chart-Energy cost per k products vs output,The unit of output is 100K.Through the comparison between output and energy cost correlation between them is reflected directly.,Oct 12,2007,29,Application practice of energy statistics&analysis in actual cost control 1,Energy budget can be made based on the result of energy statistics&analysis.Energy budget is calculated according to energy cost per k products and planned output.Due to equipment move,the output varies every month which leads to the variation of cost per k products.The cost per k products can be calculated according to the result of analysis.The difference between budget energy cost and actual cost is controlled within 5%.,Oct 12,2007,30,Application practice of energy statistics&analysis in actual cost control 2,During the week from July 2 to July 9,total consumption increased slightly while the consumption per products increased greatly.It was abnormal data and gas leakage was detected.After the leakage problem was eliminated the consumption per k products trended stable.During the week from November 21 to November 27,both total consumption and consumption per k products increased a lot which was also an abnormal data.After inspection it is found that production operator adjusted plow rate of equipment.Then after coordination with MD and Engineering,the gas flow was adjusted properly and the gas consumption came back to normal value.,Oct 12,2007,31,Y07 Energy Purchase Cost statistics,Application practice of energy statistics&analysis in actual cost control 3,Oct 12,2007,32,Experience of energy management 1,Energy management system shall be established to be applicable to all departments especially process engineering and equipment maintenance department.Potential consumption increase can be found and resolve ASAP.Energy Consumption can be controlled within a reasonable range.Coordination and cooperation between each departments is needed to effectively control the consumption.The output affects consumption per k products greatly.For fixed facility system the most efficient way to reduce energy consumption per k products is to increase production output.,Oct 12,2007,33,Experience of energy management 2,The largest energy reduction shall be process energy reduction.It is important to concern system energy saving during planning and design.Compressed air consumption will be reduced if supply is classified by pressure.But the investment will be increased.It affects the power consumption of AHU system greatly that whether building enclosure structure and temperature and humidity parameter are reasonable.It affects tap water consumption greatly that whether industrial waste water could be recycled.Process energy reduction and system energy reduction is considered as key subject in Phase II project.So the energy conservation of future completed project is guaranteed in planning and design stage.,Oct 12,2007,34,Thanks
