Similarly, taking the system power switch disk 100A and the emergency power generation switch disk 101A of the corresponding electrical device 13A as an example, when the upstream power source returns to normal (S400), the control system 12 performs the following steps of stopping the emergency power supply: stopping the slow starter 111 (S401); then disconnecting the generator control panel 110 (S402); stopping the emergency generator 11 (S403); then disconnecting the emergency power generation switch panel 101A (S404) to stop the emergency power supply of the electrical device 13A ( S405). Specifically, in the automatic mode, the control system 12 directly completes steps S401 to S405 in sequence; in the manual mode, the control system 12 graphically guides the operator to confirm one by one through the graphical interface. Steps S401 to S405 are performed.

Control process. The emergency The motor unit test 204 is a unit test of the emergency generator 11 purely by program simulation.
本發明不須依賴上游電源變電站提供電源失效信號，可自行偵測開關盤內控制電源，進而判斷上游電源系統是否失效，並回傳信號至控制系統後可通過程式邏輯作為判斷是否緊急發電機自動化供電系統功能之依據。在緊急狀況發生時，本發明之自動化緊急供電系統可自動啟動，完成緊急供電，或者由操作人員判斷緊急事故狀況並依照圖控介面手動決定最後緊急供電步驟是否執行。所述圖控介面提供簡單的操作指引，可讓操作人員放心進行緊急供電之啟動與停止，進而能夠避免傳統因操作程序的複雜導致人為疏忽而產生操作錯誤的可能性。此外，本發明之自動化緊急供電系統利用程式邏輯連鎖保護機制與開關盤間構成的電氣接點連鎖保護機制提供了雙重的連鎖保護，除了可以防止系統電源及緊急電源同時投入而導致用電危害，還可進行兩電氣設備之間二選一進行緊急供電的連鎖保護，避免緊急發電機因同時啟動兩台電氣設備而導致啟動失敗。其二選一之功能由系統自動判斷，若優先啟動之電氣設備執行異常時，可自動判斷並啟動另一電氣設備，可避免因設備故障或人為設定疏忽而造成無法完成緊急供電之憾事。此外，本自動化緊急供電系統在正常運轉時還可自動判斷欲測試設備之運轉狀態，以及啟動失敗時自動切換至另一台設備進行之緊急發電全迴路測試，其中包含自動及手動模式，便於維護人員進行日常定期保養測試。 The invention does not need to rely on the upstream power substation to provide a power failure signal, and can detect the control power in the switch panel by itself, thereby judging whether the upstream power system is invalid, and returning the signal to the control system can determine whether the emergency generator is automated through program logic. The basis of the power supply system function. In the event of an emergency, the automated emergency power supply system of the present invention can be automatically activated to complete emergency power supply, or the operator can determine the emergency situation and manually determine whether the final emergency power supply step is performed according to the graphical interface. The graphic control interface provides a simple operation guide, which allows the operator to safely start and stop the emergency power supply, thereby avoiding the possibility of an operation error caused by the inconvenience caused by the complexity of the operation procedure. In addition, the automatic emergency power supply system of the present invention provides a double interlocking protection by using a program logic interlocking protection mechanism and an electrical contact interlocking protection mechanism formed between the switchboards, in addition to preventing the power hazard caused by the simultaneous input of the system power supply and the emergency power source. It is also possible to carry out interlocking protection between the two electrical equipments for emergency power supply, so as to prevent the emergency generator from failing to start due to the simultaneous activation of two electrical equipments. The function of the second selection is automatically determined by the system. If the electrical equipment that is preferentially activated performs an abnormality, another electrical device can be automatically determined and activated, thereby avoiding the regret that the emergency power supply cannot be completed due to equipment failure or human inadvertent setting. In addition, the automatic emergency power supply system can automatically determine the operating state of the device to be tested during normal operation, and automatically switch to another device for emergency power generation full-loop test when the startup fails, including automatic and manual modes for easy maintenance. Personnel conduct routine daily maintenance tests.
綜上所述，本發明主要是利用程式化的控制系統判斷上游電源是否失效，並在失效時對應執行緊急發電機自動化供電系統功能，依序斷開系統電源開關盤，並啟動緊急發電機，將該緊急發電機產生之電源投入到緊急發電開關盤，最後緩啟動完成電氣設備之緊急供電。因此本發明可取代傳統效率低落、程序複雜的操作供電方式，並可避免系統電源恢復後與緊急發電機電源之間的衝突危害，提高系統安全性，降低工安風險。 In summary, the present invention mainly utilizes a stylized control system to determine whether the upstream power source fails, and in response to the failure to perform the function of the emergency generator automatic power supply system, sequentially disconnects the system power switch disk, and starts the emergency generator. The power generated by the emergency generator is put into the emergency power generation switchboard, and finally the emergency power supply of the electrical equipment is completed. Therefore, the invention can replace the traditional low-efficiency and complicated operation power supply mode, and can avoid the conflict hazard between the system power source recovery and the emergency generator power source, improve the system safety and reduce the safety of the work safety.
