Specifications
The software and hardware of the complex provide telemetric monitoring and control of
technological equipment from 1 to 32 monitored points (CP) from the central control center (CPU)
and perform the following functions:
initialization of the included “KP-K Equipment” at each traction substation and display on a PC monitor:
route diagrams of urban electric vehicles with the link of each section to the corresponding traction
substation;
mimic diagrams of each traction substation displaying the current state of technological equipment in accordance with the signals of the vehicle;
power consumption data for four high-voltage bushings at a traction substation;
current values in feeders of traction substation;
entering settings in “KP-K Equipment”;
transmission of up to 40 telecontrol signals (TU) from the CPU to the CP;
ensuring the retention time of the TU command from 0.2 to 4 s in accordance with the setting of the retention of teams;
transmission of up to 48 tele-signaling signals (TS) from the CP to the CPU from the DC and NC
contacts;
transmission and indication on the PC PC monitor up to 8 readings of electricity meters;
calculation of accounting of active and reactive energy in accordance with the calculated coefficient of measuring transformers;
calculation of cos φ and tg φ every hour;
transmitting from the CP to the CPU signals of television measurements (TI) of currents from 0 to 3 kA to 8 feeders of contact wires;
automatic shutdown of up to 8 feeder machines with a predetermined time characteristic of the shutdown delay;
current protection of up to eight contact wires during emergency loads in the contact network;
Note - The accuracy characteristics of the measured currents are determined by sensors DTX-3000;
automatic logging of the operator with a record of his actions to manage traction substations;
automatic maintenance of an electronic protocol for daily accounting of consumed active and reactive energy of each traction substation with the output of results every hour;
interrogation of vehicle signals of all included gearboxes in automatic polling mode or dialog mode of operator operation with each gearbox.
Note - The number of signals TU, TS, TI and feeders on the CP is agreed with the Customer.
The complex provides manual control of the functional blocks of the "Equipment KP-K" using a control device:
input and indication of execution of TU commands;
request and indication of vehicle signals;
indication of indications of measured currents in tires.
The complex is powered from a single-phase alternating current network with a voltage of 220 (± 22) V and a frequency of 50 (± 1) Hz.
The total power consumed by KP-K Equipment from a 220 V network is not more than 120 VA.
The power supply of “CP-K Equipment” at the control room and “KP-K Equipment” is provided through an uninterruptible power supply, which ensures the operation of the system when the mains
voltage is disconnected for at least 15 minutes.
