Monitoring The Load Characteristic Curve And Making Use In The Theory Loss

With social progress and development, the amount of energy to ask is more and more big, the electricity as a clean efficient, easy to transport energy, in social consumption of the total energy than also heavy more and more high, power load reached new highs, this is in power system operation management put forward higher request. Energy conservation and emission reduction, and walk the path of sustainable development has become the consensus of modern society, thus enhance power system management level, reduce the power in transmission, management has tremendous loss of economic benefits and social benefits. To load curve, and the monitoring and classification based on classification of calculate line loss theoretical calculation methods of research all have strong theoretical significance and application value. The result of the research and work done as follows:1. The power system is complex and huge, how to accurately and effective Acquisition to store huge amounts of active, reactive power, current, voltage Data has been the bottleneck of electric power systems research, although calculated Supervisory Control and Data SCADA (Acquisition) system (Data Acquisition and monitoring Control system) has been applied in parts, but the Data grid, and the measured magnitude in the interference of electric circuit is high, and cause Data collected ber restrictions. Flat rate This paper using watt-hour meter bringing RS -485 interface, with meter is developed, the device real-time communication device based on "DL/communication software T645-2007 multi-function watt-hour meter communication protocol" write, has the extensive applicability. Meanwhile SD card storage technology by large amount of data, in order to adapt to the requirement.2. The traditional load classification method are generally from physical according to need, electricity production, can supply and sales process, by sector, load in power system based on time and the distribution and classify the importance, etc. This paper is completely based on study of load curve, according to the shape of the curve of load the line classification feature based on load, classification algorithm to show that the classification more scientific and reasonable load management convenient calculation.3. The traditional loss calculation methods are based on the line every load point on the power factor. Load curve characteristic coefficient, the actual running voltage are the same under the premise of this hypothesis, and actual condition is not so, give line loss the theoretical calculation brought greater error. This paper studies the classification based on load after load characteristic curve of the loss calculation method, the line into each load the actual load characteristic curve value, effectively improve the theoretical loss calculation precision.4. To Microsoft Visio2003 graphics software development platform, using VBA for the line was designed based on the secondary development, the loss calculation classification algorithm load more loss calculation software that allows the efficient accurate, and the form of with examples of Henan somewhere by practical operation power line.
