Definitions
- the invention relates to a ship generator protection and synchronization device that records the generator values analog.
- the task is solved by digitization, which is based on analog values.
- the generator protection and synchronization device implements the generator protection with the functions:
- the fault signal signals that occur during generator protection are held until they are acknowledged by the higher-level control system or are canceled by a RESET.
- the failure of the 24 V battery voltage or a malfunction in the computer cause an unconditional message by the relay "System malfunction".
- Frequency synchronization is carried out for synchronization. After starting the unit, it is first set with permanent adjustment failed and then introduced to the mains frequency with long and short pulses. The comparison of whether the grid frequency is higher or lower than the generator frequency is also carried out on the generator protection and synchronization device.
- the length of the HIGHER / LOWER adjustment impulses can be changed on the control panel.
- the floating voltage obtained from the synchronization device is advantageously evaluated.
- the floating voltage is generated by comparing the mains and generator voltages. According to the difference f gene. and f-net also changes the slope of the levitation voltage. The slope of the levitation voltage curve obtained from the measured values is evaluated and the switch-on command is issued with the appropriate lead.
- the difference frequency between the mains and generator frequency is also derived from the floating voltage.
- the synchronization is locks.
- the HIGHER / LOWER adjustment impulses are completely blocked, since there can only be a fault in the unit.
- Limit value of the differential frequency for the release of the adjustment impulses e.g. 10 Hz
- Limit value of the differential frequency for the changeover of continuous and long impulses e.g. 1.5 Hz
- Limit value of the difference between the generator voltage and the mains voltage for blocking the adjustment and switching on the generator switch The generator switch is blocked when the voltage difference is too great. If the voltage difference is above a limit value to be set, the connection of the generator switch and the output of the adjustment pulses are blocked. Exceeding the limit value is signaled by an LED on the front of the device.
- a voltage regulator can be provided in the SIMATIC-S7, which outputs higher / lower adjustment pulses to the voltage regulator of the generator.
