焦化發電機組可以實現多組并聯。發電機組并聯運行是一種常見的技術手段，旨在提高電力系統的可靠性和靈活性。對于焦化發電機組而言，同樣可以通過并聯控制器等設備實現多臺發電機組的并聯運行。

Coking power generation units can achieve multiple parallel connections. Parallel operation of generator sets is a common technical means aimed at improving the reliability and flexibility of power systems. For coking power generation units, parallel operation of multiple units can also be achieved through devices such as parallel controllers.

在實現焦化發電機組并聯時，需要注意以下幾點：

When implementing parallel connection of coking power generation units, the following points should be noted:

參數匹配：確保參與并聯的發電機組在電壓、頻率、相序、功率等參數上相匹配。這是實現并聯運行的基礎，可以避免因參數差異導致的電流不平衡、功率波動等問題。

Parameter matching: Ensure that the generator sets participating in parallel are matched in terms of voltage, frequency, phase sequence, power, and other parameters. This is the foundation for implementing parallel operation, which can avoid problems such as current imbalance and power fluctuations caused by parameter differences.

接線正確：將多臺發電機組分別接入同一個接線盒，并確保接線正確無誤。在接線過程中，需要遵循電氣安全規范，確保接線的牢固性和可靠性。

Correct wiring: Connect multiple generator sets to the same junction box and ensure correct wiring. During the wiring process, it is necessary to follow electrical safety regulations to ensure the firmness and reliability of the wiring.

并聯控制器：使用并聯控制器進行發電機組的并聯控制。并聯控制器可以自動同步各發電機組的輸出電壓和頻率，實現負荷的均分和穩定運行。同時，并聯控制器還具備數據測量、報警保護及遠程監控等功能，可以提高系統的安全性和可維護性。

Parallel controller: Use a parallel controller for parallel control of the generator set. Parallel controllers can automatically synchronize the output voltage and frequency of each generator set, achieving load sharing and stable operation. At the same time, the parallel controller also has functions such as data measurement, alarm protection, and remote monitoring, which can improve the safety and maintainability of the system.

檢查與測試：在并聯運行前，需要對各發電機組進行單獨測試，確保其性能正常。并聯運行后，還需要定期檢查各發電機組的運行狀態和參數，確保系統的穩定運行。

Inspection and testing: Before parallel operation, each generator unit needs to be tested separately to ensure its normal performance. After parallel operation, it is necessary to regularly check the operating status and parameters of each generator set to ensure the stable operation of the system.

綜上所述，焦化發電機組可以通過合理的參數匹配、正確的接線、使用并聯控制器以及定期的檢查與測試等措施實現多組并聯運行。這不僅可以提高電力系統的可靠性和靈活性，還可以降低運行成本和維護難度。

In summary, coking power generation units can achieve multi group parallel operation through reasonable parameter matching, correct wiring, use of parallel controllers, and regular inspection and testing measures. This can not only improve the reliability and flexibility of the power system, but also reduce operating costs and maintenance difficulties.
