Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Control system and diagnostic equipment substation information and measurement systems of electricity metering A.A. SOLDATOV We propose a scheme for the construction of automated equipment control systems and diagnostic equipment Information and measuring accounting complexes of electricity substations regional grid companies. Described shortcomings exploited the technical and commercial accounting of electric power systems of defining a possible basis for the add-diagnostics system. The approaches to the reduction of energy losses in networks of distribution grid companies by analyzing power imbalances. Assumed control and diagnostic information and measurement of electric power metering systems work on the principle of calculating the unbalance current, voltage, power at the input and outgoing connections of the substation section. monitoring and diagnostics system consists of a client-side, having a device collection instantaneous current-voltage state electricity meters in section and a device to send the data to the Internet, as well as the server side – workstation in the form of a personal computer with special software, with links to the Internet for receiving information from the substation and processing. Typical design standards and the organization of the electricity metering system substations suggest the widespread use of model control and diagnostic systems in the distribution network companies of the country. An algorithm sectional diagnosis of the state accounting of substation power system based on the detection of imbalances of electricity based on the requirements and conditions imposed on the Information-measuring complex accounting. Keywords: ensuring correct accounting of electric power substations by sectional control imbalances of power, currents, voltages. Contacts: E-mail: aa.soldatov@bk.ru Pp. 01-07.
