Power-Saving Mode Of Large-Scale Shipbuilding Enterprises Of Research And Verification

Peak and valley price is an economic measure which is used in the electricity industry to remove the peak load and to improve load rate and system stability.Towards the time of use power price,the paper analyses its domestic and overseas research status,and sets forth the theory foundation and rules for how to establish TOU power price;Considering the aim and risk of power supply company when implementing the TOU price,the paper analyses the influencing factors,puts forward the method of how to establish the price system reasonably,proposes some strategies of how to control the risk.This topic is rests on in our country large-scale ships industry actual production condition to use electricity the question, falls this gain in view of the country, saves the production energy consumption the specification, the improvement production management pattern, the solution at present power supply question. The topic take the company to the electrical power system specification as a foundation, and used electricity the load tendency based on the production characteristic to establish Chops Wave ridge to fills in the valley the new production pattern, the paper elaborated this pattern principle of design and the constitution way, has established the corresponding mathematical model, and proposed other like tentative plan and so on frequency conversion electricity saving, illumination electricity saving. At the same time, this topic analyzed and has solved the quality question which in the present electrical network exists, in detail elaborated the overtone government technology project application. This system after tries the movement, carries on the data statistics after the long time to the energy consumption, has carried on the appraisal to this system movement reliability, also the energy consumption range of fall and the electrical network quality conform to the design requirement. Basing on the research of theory,it gives a practical analyses of a certain power accepting company's actual application. Large industrial end-users in the corresponding increase in equipment investment and to take appropriate management and technical measures can have a strong regulatory function of the grid, use electricity price to make up for the end-user participation in the Netherlands and the grid transfer cost will enable end-user the Peak cutting and Valley filling conscious. The use of-use electricity price policy, systems analysis of the load characteristics of enterprises, production characteristics and technological process; optimize the power consumption using a variety of means, the full implementation of measures the Peak cutting and Valley filling. At the same time, analysis of this issue and resolve the current quality of the existing power grid problems, the harmonic detail engineering management technology. Of the system in trial operation, theAfter a long-term data on energy statistics, the operation of the system to carry out an assessment of the reliability and decrease energy consumption and power grid in line with the quality of the design requirements. The main work of this paper include the following:①A ship's work to promote the concept of power; the company's analysis of electricity consumption; the Peak cutting and Valley filling reduce the energy consumption of the theoretical research and is derived, the establishment of a mathematical model the Peak cutting and Valley filling, perfected the Peak cutting and Valley filling assurance system; for reasonable production organization to make recommendations and provide the corresponding theory.②Ship for the current energy problems in enterprises, the actual problems encountered in the production of an analysis of the quality of the integrated power system testing, the true face of the company work in promoting energy conservation to the attention of harmonics, surges and other problems .③Source solution for improving the frequency welding machine, the purpose is to achieve energy conservation and improve the quality of power grids. Selection of a professional harmonic absorption device, the work of the company's energy-saving benefits, the company brought about by the protection of highly sensitive equipment.④Lighting energy saving work. Practice in the production process, the introduction of Saver, the company's energy-saving products have been used for data analysis and statistics and reach a conclusion.The above work was completed installation and acceptance of work, energy-saving work carried out statistical analysis of data through the production of practice, informed of the effectiveness of energy-saving energy-saving measures, the company's power management can result in concrete positive results. Practice through a series of data, the production management company offering constructive suggestions.
