#NEPLAN BUS HOW TO#
The details about how to achieve radiality will be explained in the methodology section. In order to satisfy this, all the loads at the network has to be supplied by a single source and none of the loads should be left unfed. Another constraint of the reconfiguration method used in this study is, maintaining the radial operation of the system. nTsw is number of tie switches that has to be opened, represented by (6) where, I max(i,k ) is the current carrying capacity of branch from bus i to bus k, V min(i) and V max(i) are the minimum and maximum allowed voltages at bus i respectively.

During switching, radially of the network is checked by comparing the number of open switches with the number of tie switches. (5) |(, )| ≤ (, ) nline is number of lines given by (,) = () (,) ∗ () ≤ () ≤ () = − 1 (8) where v, nnode are numbers of vertices and nodes respectively The number of tie switches need to be opened can be calculated according to (7). The constraints defined for this reconfiguration method are the current carrying limits of the lines, the voltage boundaries of the network and the ratings of the equipment. Apparent power flow bus I to bus k given b y (4) = − 1 where, I (i,k ) is current flow from bus I to bus k. The apparent powers flowing through branches are evaluated with the bus voltages and branch currents obtained from load flow calculations. 1, February February 2016 Reconfiguration of Actual Distribution Network with Optimum Power Flow for Loss Reduction İlker Dursun and Feyzi Karaosmanoğlu Bogazici Electricity Distribution Company, İstanbul, Turkey Email: (3) where, S (i,k ) is apparent power flow bus i to bus k.

The standard form that how the unit symbol and multiplier should be saved in CIM-RDF-XML I'm not sure.International International Journal Journal of Electronics Electronics and Electrical Electrical Engineering Engineering Vol. Please find below a complete list of the used Neoplan bus/Coach for sale. In both case, the CIM-XML-Parser was failed.

So the CIM-XML-Parser can not get the right unit as well, which just uses default unit symbol. In addition to Cimphony : Bus 1 HV Bus 10 LV 20.00 Īs you seen the HV and LV Unit set Information written in the Bus 1 HV & Bus 10 LV ( meanwhile with whitespace parsering problem! I just replaced whitespace into "_" before). It seems nothing about unit, maybe the information about LV and HV can be saved in the IdentifiedObject.name:407īut other Simulation Softwares like PowerFactory and Cimphony and examples from GridData also use an informal way: Cimphony & PowerFactory: 33.0KV 33 ģ3.0KV was written directly in the IdentifiedObject.name, but the value of nominalVoltage is lack of unit. In CIM defined: mutiplier + UnitSymbol = Unit, for example: "k" + "V" = "kV"įirst of all I found that in the CIM-RDF-XML file from Neplan there is no UnitSymbol and Unit Mutiplier because in Neplan has predefined the "HV" and "LV" unit sets. Unit System in CIM-RDF-XML and Modelica are different so i need to translate them.
