За предыдущие годы сформировалось большое количество методов получения установившего режима на базе телеметрии (оценивания состояния), которые основаны на учете измерений только модулей этих величин, а также значений активной  и  реактивной  составляющих  мощностей  инъекций  в  узлах  и  перетоков  в ветвях. Большая часть этих методов основывалась на методе взвешенных наименьших квадратов или других методах, основанных на методе максимального правдоподобия, для которых требуется определение весовых коэффициентов измерений, традиционно выбираемых на основе относительных погрешностей этих измерений. Однако имеется проблема    учета    измерений    электрических    углов,    для    которых    относитель ная погрешность оказывается принципиально неопределимой. Также существует проблема, связанная с  объединением измерений СВИ с  традиционными средствами измерени й  в единую измерительную систему, ввиду существенного различия в точности и частоте обновления. В работе предложен подход для объединения средств СВИ с традиционными средствами измерения SCADA в рамках процедуры оценивания состояния, учитывающий изложенные проблемы.</p></abstract><trans-abstract xml:lang="en"><p>In  modern power systems, the special kind of measurement systems was actively implemented for the last 20 years. These measurement systems have a high-precision synchronized time stamp, which makes it possible to obtain, in addition to the effective value of line current and bus voltage, the electrical phase angles. In previous years, a large number of methods for obtaining a steady state based on telemetry (state estimation) have been formed, which are based on taking measurements of only the modules of these quantities, as well as the values of the active and reactive components of injection power in the nodes and flows in the branches. Most of these methods were based on the weighted least squares method, or other methods based on the maximum likelihood method, for which determination of the weighting factors of measurements, traditionally chosen on the basis of relative errors of these measurements, is required. However, there is the problem of taking measurements of electrical angles, for which the relative error is fundamentally indeterminable. There is also a problem associated with the integration of measurements of phasor measurements with traditional measurement tools into a single measuring system due to a significant difference in accuracy and update frequency. The paper proposes an approach for combining phasor measurements with traditional SCADA measurements in the framework of the state estimation procedure, taking into account the problems described.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>статическое оценивание состояния</kwd><kwd>синхронизированные векторные измерения (СВИ)</kwd><kwd>метод максимального правдоподобия</kwd><kwd>выбор весовых коэффициентов</kwd><kwd>линейное оценивание состояния</kwd></kwd-group><kwd-group xml:lang="en"><kwd>static state estimation</kwd><kwd>synchronized vector measurements</kwd><kwd>maximum likelihood estimation</kwd><kwd>choice of weights</kwd><kwd>linear state estimation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">D.A.
