摘要： A method performs state estimation of a distribution network based on real time measurement values. The method includes calculating load scaling factors at least for non-redundantly measurable parts of the distribution network, determining whether each of the load scaling factors related to a non-redundantly measurable part of the distribution network is within a given range (RLSF), and discarding the measurement values related to the corresponding scaling factor for all load scaling factors outside the given range (RLSF). The network state of the distribution network is then estimated based on the remaining measurement values.

摘要： The invention relates to a method for operating an energy distribution grid (10), in which energy is fed through substations (U1, U2, U3, U4) into subnetworks (TN1, TN2, TN3, TN4) and the distribution of the energy is monitored by a central device (Z) which is superordinate to the substations (U1, U2, U3, U4). In accordance with the invention, provision is made for at least one of the substations (U1, U2, U3, U4) to be operated in an optimization mode, in which said substation, in order to optimize the operation of the entire energy distribution grid (10), investigates a modification action which could be performed by the substation (U1, U2, U3, U4) in the subnetwork (TN1, TN2, TN3, TN4) assigned thereto for the effect of this modification action on the operating state of the entire energy distribution grid (10), wherein the substation (U1, U2, U3, U4) operated in the optimization mode receives, from the substation(s) affected by the modification action or from all substations (U1, U2, U3, U4), in each case one substation-individual sensitivity value (Q1, Q2, Q3, Q4, ∂
Fl 1/∂C, ∂
Fl 2/∂C, ∂
Fl 3/∂C, ∂
Fl 4/∂C), which indicates the change in the local operating state in the subnetwork (TN1, TN2, TN3, TN4) assigned to the respective other substation (U1, U2, U3, U4) if the modification action were to be implemented in the subnetwork (TN1, TN2, TN3, TN4) of the substation (U1, U2, U3, U4) operated in the optimization mode, and the substation (U1, U2, U3, U4) operated in the optimization mode checks, on the basis of the received sensitivity values (Q1, Q2, Q3, Q4, ∂
Fl 1/∂C, ∂
Fl 2/∂C, ∂
Fl 3/∂C, ∂
Fl 4/∂C), whether the modification action would result in an improvement of the operating state for the entire energy distribution grid (10).-

摘要： The invention relates to a method for determining load flow in a symmetrical electrical supply grid, particularly a symmetrical electrical distribution grid having asymmetrical loads. The load flow is typically solved within an electrical supply grid by means of an extensive matrix system. The determination of power, voltage, and current at certain node points in the electrical supply grid leads to a large matrix to be solved, which previously had to be solved in whole using algebraic means. By converting the matrix to symmetrical space vector components that can be used to monitor the phase progression of the space vector components, it becomes possible to divide the entire matrix into partial matrices and thus to be able to calculate said partial matrices faster and in parallel using a computer system.

摘要： The invention relates, inter alia, to a method for operating an energy distribution network (10) where the energy distribution is monitored by at least one control device. In order to optimise the operating state of said energy distribution network (10), modification actions are implemented with the aim of improving the operating state of said energy distribution network (10). According to the invention, prior to implementing a modification action, the control device verifies whether the amount of improvement in the operating state of the energy distribution network (10) outweighs the amount of wastage from the energy distribution network (10) caused by implementation of the modification action, and only implements said modification action when this is the case.

摘要： The invention relates to a method for producing a state signal (Sz) that indicates a state of an energy transmission system, whereby, for pre-determined network nodes of the energy transmission system, electrical measuring values for at least one electrical measuring variable are measured and used to produce the state signal indicating the state. According to the invention, respectively predicted load data that predict the electrical behaviour of the respective load are associated with the electrical loads connected to the energy transmission system; the electrical loads are respectively associated with an electrical load group into which the electrical loads are collected with comparable prognosis reliability; an individual weighting value that describes the prognosis reliability of the predicted load data of the loads associated with the load group is respectively allocated to each load group; and the state signal is formed using the measuring values, the load data and the weighting values.
