For now i'm trying very big project on ep20k1000ebc-652-1x and i'm afraid that overheating will damage my FPGA.
Is there any automatic defense in my FPGA that preventing damage by overheating and will shutdown or reset FPGA?

Nothing unless you add it yourself.
For example, in this Stratix II design:
http://www.ovro.caltech.edu/~dwh/carma_board The FPGA thermal diodes are monitored using I2C devices, and the alert pins on those devices are used to shut-off power to the FPGAs. Current sensors (INA209s) are first set to a maximum current expected for the design, and are then enabled. If the design uses more-than-expected current, then the power is shut-off.
If you want a robust system, then you'll want to design something similar into your hardware. If you are using pre-existing hardware, then you need to review the hardware schematics to see if there is anything you can use to sense over-temperature and then at least reset the FPGA.
