2 TracFeed® Simulation REFERENCE

Input data to the TracFeed® Simulation program consists of data defining track, trains and how they are used together as well as data for controlling the calculations and the output. The data are arranged in groups with a specific name which is referred to in the input. The groups are to be specified in the normal SIMPOW input files. The following data groups are valid: - TRAINS

Train data

- TRACK

Track data including stations and speed limits

- DRIVE PATH

Connects track sections to drive paths for trains

- TIMETABLE

Defines how the trains traffic the drive paths

The data groups are described in the following. The first data, following the model name, for an individual model in a group is the identification name . This identification is used through the whole program when referring to the element.



Parameter names (in bold capitals in this manual) followed by the parameter value should be given in dynpow file to specify the parameter value. The figure in italics below the parameter name is the default value. If the parameter is not given the default value is used. Parameters without default value must be given. All identifier names must start with a letter ("a"-"z" or "A"-"Z") From the second position in the name following characters is allowed: "a"-"z", "A"-"Z", "0"-"9", "_" and "-". Time can be specified in different formats. They are specified equally for both time points and time intervals. All formats is converted to seconds within the simulation. Simulations are always started at time=0s. Following formats are valid (examples): "6524" - 6524 seconds "03:30" - 3 hours and 30 minutes (This NEVER means 3 minutes and 30 seconds.) "03:30:02" - 3 hours 30 minutes and 2 seconds. "03:30 day 2" or "day 2 03:30 " - 2 24 + 3 hours and 30 minutes "03:30:02 day 2" or "day 2 03:30:02 " - 2 24 + 3 hours, 30 minutes and 2 seconds

The parameters can theoretically be obtained through measurements without knowing anything about its inner structure. Default values are given beneath the parameters with Italics. Parameters without defaults must be set. Text enclosed by is to be replaced by user input. Definition of an DC Machine AC Train: THYRISTORTRAIN {} Name (id) of the DC Machine AC Train, must start with a letter. List of train parameters and data, specifying train with name . Here follows the DC Machine AC Train parameters enclosed by {}: { DYNMASS 1.1 MASS if MASS is set Dynamic mass [metric tons] of train, including load. MASS DYNMASS if DYNMASS is set Mass [metric tons] of train, including load. 

ADHMASS MASS Adhesion mass [metric tons] of train. Adhesion mass is the total mass on driving axles. The maximum tractive effort with respect to adhesion is calculated as: F [kN] = adhesion g ADHMASS where g = 9.81 m/s2. MAXSPEED Maximum speed [km/h]. SPEEDM 0 Speed margin, determines how fast the train may travel compared to the speed profile for the track. Unit is set by SPEEDMSORT. SPEEDMSORT KM/H Unit for SPEEDM. May be REL or KM/H. REL means that SPEEDM is given as a factor relative to the speed profile (Track speed 80km/h, SPEEDM 1.1 and SPEEDMSORT REL gives highest allowed train speed 88km/h.). KM/H means that SPEEDM is given in km/h (Track speed 80km/h, SPEEDM -15 and SPEEDSORT KM/H give highest allowed speed 65km/h.).

The no load losses of the main transformer are not included here, as they are included in P0. PFAUX 1.0 Power factor [ ] at zero speed for auxiliary power, train heating and air condition which is taken directly from the main transformer. Corresponds to PAUXT. The power factor is assumed to be lagging. The power factor must be higher than 0. BRIDGES Number of converter bridges in series with one motor. This is of importance to determine the reactive power when all the bridges have not full advanced angle. UMOTMAX 100 The maximum allowed voltage between the motors terminal under the worst conditions, that is generally with high engine speed. The value is varying with the speed.The value is given in per centage FIRSTLIM flux 

Normally the first limitation for a DC current motor is that with increasing speed the inductive emf reaches a value close to the applied voltage and the flux has to be reduced . However for same motors the anchor current has to be reduced before the reduction of flux when the speed is increased. This is vital since the decrease of anchor current is independent of the voltage compared with the reduction of the flux. The value is then CURRENT BASESPEED The value of the trains speed when the motor has reached the base point at nominal voltage. The base point is defined as the moment when the flux has to be reduced to enable the motor to produce a tractive effort at higher speed. BASECOSFI The power factor of the motor when the control is with fully advanced angle, that is the motor speed has passed the base speed.

A list of lines containing specifications of speed limits. This data is line orientated. First in a line the position [km] is given. A speed limit must be given for the start position. In the SPEEDPROFILE-list you give the speed limit that is valid in an interval in "uptrack" direction ( increasing "km") and you can give both U and D on the same line for the same speed limit. In the SPEEDSIGN-list you give the speed limit that is valid in an interval in "uptrack" direction ( increasing "km") and the speed limit that is valid in an interval in "downtrack" direction ( decreasing "km"). Therefore you must give U and D on different lines because they have different speed limits. A track section can have several SPEEDPROFILE (or SPEEDSIGN) lists. { Position [km] in section. Must be given first in each line in the list. U Indicates that data in this line applies to trains travelling uptrack. D Indicates that data in this line applies to trains travelling downtrack. SPEED Speed limit [km/h]. } STATIONS {} 



Name of stations list. A list of lines containing specifications of stations. This data is line orientated. First in a line the position [km] is given. Then follows data for travelling direction, dwell times and earliest departures. A track section can have several STATIONS lists.

{ Position [km] in section. Must be given first in each line in the list. U Indicates that data in this line applies to trains travelling uptrack. D Indicates that data in this line applies to trains travelling downtrack. Note: If neither U nor D is set, line will be ignored.

WAIT Dwell time [s] at station. The sum of actual time and WAIT is compared with EARLIEST in order to calculate the departure time after stop at a station, see EARLIEST below. EARLIEST 0 Time [s] for earliest departure from a station. If a train stops at a station, the departure time is equal to EARLIEST, if EARLIEST is longer than actual time + WAIT. The departure time is equal to actual time + WAIT, if EARLIEST is shorter than actual time + WAIT. EARLIEST is given relative start of simulation. } Customer Doc. No Our Ref
