● The code references ZDistA_komp.c which is missing. Let me check mocks.c for the implementation.
|
||
|
||
● Read 1 file (ctrl+o to expand)
|
||
|
||
● The problem is that ZDistA_komp.c is missing - it's referenced in test_wrapper.c (line 2) but doesn't exist in the project directory. This file should contain the actual distance protection algorithm.
|
||
|
||
Without this file, the DLL cannot be compiled. Here's what you need:
|
||
|
||
1. Provide ZDistA_komp.c - The main distance protection algorithm source file
|
||
2. Compile the DLL - Once you have the source, compile it with:
|
||
gcc -shared -o zdist_model.dll test_wrapper.c mocks.c -lm
|
||
|
||
The Python libraries are already installed. Once you have the missing C source file and compile the DLL, the tester should work.
|
||
|
||
Do you have the ZDistA_komp.c file, or would you like help creating a stub implementation to test the Python script?

|
||
- Red line: Trip signal from the stub relay - it trips when current exceeds the 5.0 threshold
|
||
|
||
The COMTRADE file was successfully read and processed. The stub implementation:
|
||
|
||
1. Reads the COMTRADE files (.CFG and .DAT)
|
||
2. Processes data using Full-Cycle DFT filter
|
||
3. Calculates symmetrical components
|
||
4. Runs a simple overcurrent trip algorithm
|
||
5. Generates the result plot
|
||
|
||
You can now expand the RelayStub class in tester.py to implement the actual distance protection algorithm logic.

|

● Read 1 file (ctrl+o to expand)
|

|

● The tester is now processing all three phases. Looking at the plot:
|
||
|
||
- Top subplot: Shows currents for all three phases (L1-blue, L2-green, L3-orange)
|
||
- Bottom subplot: Shows trip signals for each phase
|
||
|
||
The fault occurs around 0.04s on phase L1 (blue current spikes), and the stub relay trips on L1-E. Phases L2 and L3 don't trip because their currents remain below the 5.0 threshold.
|
||
|
||
The L2 and L3 phases are fully integrated. Would you like me to adjust the stub logic or the plot display?

1. Top subplot: Phase currents (I_L1, I_L2, I_L3)
|
||
2. Middle subplot: Phase voltages (U_L1, U_L2, U_L3) - you can see the voltage drop around the fault at 0.04s
|
||
3. Bottom subplot: Trip signals for each phase
|

The voltages clearly show the fault effect - they drop significantly when the short circuit occurs around 0.04s on phase L1.

1. Top: Phase currents

2. Second: Phase voltages
|

3. Third: Impedance components (R and X for each phase)
|
||
4. Bottom: Trip signals
|
||
|
||
The impedance plot shows the fault clearly:
|
||
|
||
- Before fault (~0.02-0.04s): Normal load impedance values
|
||
- During fault (~0.04s+): L1 impedance (blue) drops to near-zero (short circuit)
|
||
|
||
The R and X values for L1 (blue) drop significantly when the fault occurs, which is expected behavior for a distance protection relay.

|
||
1. Prądy - Fault na L1 ok. 0.04s
|
||
2. Napięcia - Spadek napięcia podczas zwarcia
|
||
3. Impedancje - Spadek do ~0Ω podczas zwarcia (L1 - niebieski)
|
||
4. Trip - Sygnał wyłączenia
|
||
|
||
Algorytm zawiera:
|
||
|
||
- Strefa 1 (natychmiastowa): R=8Ω, X=16Ω
|
||
- Strefa 2 (300ms): R=16Ω, X=32Ω
|
||
- Strefa 3 (600ms): R=24Ω, X=48Ω
|
||
- Charakterystyka wielokątna z kątem 75°
|
||
- Detekcja kierunku (uproszczona)

● Wynik:
|
||
|
||
- 0.04s - Początek zwarcia na L1
|
||
- Napięcie L1 spada do ~0V podczas zwarcia
|
||
- Impedancja L1 spada do ~0Ω (prąd zwarciowy)
|
||
- Trip L1 sygnalizuje wyłączenie
|
||
|
||
Algorytm zabezpieczenia odległościowego działa poprawnie - wykrywa zwarcie na podstawie pomiaru impedancji i wysyła sygnał trip.

|
||
The impedance plot shows the fault clearly:
|
||
|
||
- Before fault (~0.02-0.04s): Normal load impedance values
|
||
- During fault (~0.04s+): L1 impedance (blue) drops to near-zero (short circuit)
|
||
|
||
The R and X values for L1 (blue) drop significantly when the fault occurs, which is expected behavior for a distance protection relay.

|
||
1. Prądy - Fault na L1 ok. 0.04s
|
||
2. Napięcia - Spadek napięcia podczas zwarcia
|
||
3. Impedancje - Spadek do ~0Ω podczas zwarcia (L1 - niebieski)
|
||
4. Trip - Sygnał wyłączenia
|
||
|
||
Algorytm zawiera:
|
||
|
||
- Strefa 1 (natychmiastowa): R=8Ω, X=16Ω
|
||
- Strefa 2 (300ms): R=16Ω, X=32Ω
|
||
- Strefa 3 (600ms): R=24Ω, X=48Ω
|
||
- Charakterystyka wielokątna z kątem 75°
|
||
- Detekcja kierunku (uproszczona)

|
||
- 0.04s - Początek zwarcia na L1
|
||
- Napięcie L1 spada do ~0V podczas zwarcia
|
||
- Impedancja L1 spada do ~0Ω (prąd zwarciowy)
|
||
- Trip L1 sygnalizuje wyłączenie
|
||

Algorytm zabezpieczenia odległościowego działa poprawnie - wykrywa zwarcie na podstawie pomiaru impedancji i wysyła sygnał trip.

rec.load("zwarcie_testowe.cfg", "zwarcie_testowe.dat")
|
||
|
||
- Wczytuje pliki w formacie COMTRADE (standard IEC 60255-24)
|
||
- CFG - plik konfiguracyjny z metadanymi
|
||
- DAT - plik z danymi próbek
|
||
|
||
2. Ekstrakcja sygnałów

||

|
||
|
||
Cel: Wyodrębnienie fundamentalnej składowej (50 Hz) z sygnału próbek.
|
||
|
||
- Okno N próbek (20 próbek przy 1000 Hz = 1 okres)
|
||
- Oblicza składową rzeczywistą (Re) i urojoną (Im)
|

- Daje wektor fazorowy: I = Re + j·Im

|
||
I2pr = (I1 + a2*I2 + a*I3) / 3 # Składowa przeciwna
|
||
|
||
Zastosowanie: Do detekcji kierunku i różnych typów zwarć.

5. Obliczanie impedancji

● Program przetworzył 26 rejestracji. Są błędy dla niektórych plików:
|

|

- Błędy kodowania (polskie znaki)
|

- Błędy przy częstotliwości próbkowania
|

Naprawię te problemy w tester.py.
