    network Available redundant measurements are used for estimation of this vector i e voltages currents real and reactive power However the calculation algorithms are valid only for simultaneously measured data The inexactness of measured quantities comes from errors of individual parts of measuring chain in the switching station control system Another source of errors is asynchronous measurement of measured quantities and data delay in communication lines All these errors mean aggravation of exactness of calculations Relative phasors between network nodes are specific variables Methods of their measurement are synchronous by principle and they are not dependent on the error of amplitude The demands on their quality differ according to the way of their utilization Optimization of utilization of distribution networks with high load raises need of real time knowledge of actual steady operation and dynamic transitions Asynchronous real time measurement brings considerable errors to subsequent control processes and control system calculations Devices for synchronous measurement of voltage and current phasors improved communication between objects and dispatching centre and powerful computer hardware represent the solution of these problems Synchronous measurement plays key role for the estimation of high voltage network Practical experience shows that delay of information concerning changed measurement can

    is implemented in the distribution network 110 kV A short time verification operation and testing was performed in 2007 in the transmission network 400 220 kV The system is based on measurement and processing of three phase synchronous phasors of voltage and current The METEL PMU units used for measurement in the system measure the synchrophasors at fifty times per second rate i e with 20ms period The units conform to the international standard IEEE C37 118 2005 and they are fully comparable with other PMUs meeting the same standard The entire system is flexible and another user specific functions and application can be tailor made in the case of implementation of PMU WAMS in the specific networks The data from individual PMUs are sent to the central station where they are processed in real time and archived All communications meet the above stated standard A phasor data from other electric systems can be also processed in the system and the central station can send and receive data from a dispatcher control system The system functions allow to process and monitor data according to various user requirements e g monitoring of quick dynamic transient actions or slowly changing states of network components like line parameters User can work on line or export data for processing in other systems The outputs of individual software applications are visualized in the user client workstations connected to the central station The system is designed as open for all level cooperation with components or systems supplied by other suppliers and for effective complement of the control system functions There are a number of functions and applications available in WAM METEL system e g adviser for safety switching in high voltage networks monitoring of complex voltages and currents amplitudes and angles in and between network nodes
