饋線保護(hù)測控裝置是電力系統(tǒng)中的一個重要保護(hù)設(shè)備，REF615主要用于饋線發(fā)生短路、接地故障或其他異常情況時，快速切除故障，保護(hù)電力系統(tǒng)的穩(wěn)定運行。

饋線保護(hù)測控裝置可以感應(yīng)電力系統(tǒng)中的異常電流、電壓信號，與事先設(shè)定的故障保護(hù)條件進(jìn)行比較，當(dāng)檢測到故障時實現(xiàn)快速切斷故障環(huán)節(jié)，防止故障向電網(wǎng)擴(kuò)散。

此外，饋線保護(hù)測控裝置還具有其他多種功能，如瞬時電流速斷、限時電流速斷、定時限過流、過負(fù)荷、低頻減載、檢無壓三相一次重合閘、控制回路斷線告警等。

總之，饋線保護(hù)測控裝置在電力系統(tǒng)中發(fā)揮著重要作用，能夠保障電網(wǎng)的穩(wěn)定運行和電力供應(yīng)的安全可靠。

除了上述的快速切除故障、保護(hù)電力系統(tǒng)的穩(wěn)定運行等主要功能外，饋線保護(hù)測控裝置還有以下用途：

故障定位：饋線保護(hù)測控裝置可以通過分析故障時的電流、電壓等信號，快速準(zhǔn)確地定位故障所在的區(qū)段，為故障的快速處理提供重要信息。

故障類型識別：饋線保護(hù)測控裝置可以識別不同類型的故障，如短路、接地故障、斷線等，有助于對故障進(jìn)行針對性的處理。

通信功能：饋線保護(hù)測控裝置具備與其他設(shè)備進(jìn)行通信的能力，可以接收調(diào)度指令、發(fā)送故障信息、實時監(jiān)測數(shù)據(jù)等，實現(xiàn)電網(wǎng)的智能化管理。

自動重合閘：饋線保護(hù)測控裝置可以實現(xiàn)自動重合閘功能，即在故障發(fā)生后，自動斷開并重新合上斷路器，嘗試恢復(fù)供電。這有助于提高供電的可靠性。

負(fù)荷管理：饋線保護(hù)測控裝置可以監(jiān)測負(fù)荷的變化，對過載或輕載情況進(jìn)行預(yù)警或調(diào)整，確保電網(wǎng)的負(fù)荷平衡和穩(wěn)定。

越限報警：當(dāng)電流、電壓等參數(shù)超過設(shè)定值時，饋線保護(hù)測控裝置可以發(fā)出越限報警信號，提醒運維人員及時處理。

備自投功能：在備用電源正常情況下，饋線保護(hù)測控裝置可以實現(xiàn)自動投入備用電，提高供電的可靠性。

綜上所述，REF615 饋線保護(hù)測控裝置在電力系統(tǒng)中具有多種用途，不僅可以快速切除故障、保護(hù)電力系統(tǒng)的穩(wěn)定運行，還可以實現(xiàn)故障定位、故障類型識別、通信、自動重合閘、負(fù)荷管理、越限報警以及備自投等功能。這些功能的實現(xiàn)有助于保障電網(wǎng)的穩(wěn)定運行和電力供應(yīng)的安全可靠。

REF615 饋線保護(hù)測控裝置可以實現(xiàn)自動重合閘功能

Feeder protection measurement and control device is an important protection equipment in the power system, REF615 is mainly used to quickly remove the fault when the feeder occurs short circuit, ground fault or other abnormal conditions, to protect the stable operation of the power system.

The feeder protection measurement and control device can sense the abnormal current and voltage signal in the power system and compare it with the preset fault protection conditions. When the fault is detected, it can quickly cut off the fault link and prevent the fault from spreading to the power grid.

In addition, the feeder protection measurement and control device also has a variety of other functions, such as instantaneous electrical flow rate break, limited time electrical flow rate break, fixed time over current, over load, low frequency load reduction, three-phase voltage detection and non-reclosing, control loop break alarm.

In short, the feeder protection and control device plays an important role in the power system, which can ensure the stable operation of the power grid and the safety and reliability of the power supply.

In addition to the above main functions such as rapid fault removal and stable operation of the power system, the feeder protection measurement and control device also has the following uses:

Fault location: The feeder protection measurement and control device can quickly and accurately locate the fault section by analyzing the current and voltage signals during the fault, which provides important information for rapid fault processing.

Fault type identification: The feeder protection measurement and control device can identify different types of faults, such as short circuit, ground fault, broken line, etc., which helps to deal with the fault.

Communication function: The feeder protection measurement and control device has the ability to communicate with other devices, and can receive scheduling instructions, send fault information, real-time monitoring data, etc., to realize the intelligent management of the power grid.

Automatic reclosing: The feeder protection measurement and control device can realize the automatic reclosing function, that is, after the fault occurs, automatically disconnect and re-close the circuit breaker to try to restore power supply. This helps to improve the reliability of the power supply.

Load management: The feeder protection measurement and control device can monitor the change of load, early warning or adjustment of overload or light load to ensure the load balance and stability of the power grid.

Off-limit alarm: When the current, voltage and other parameters exceed the set value, the feeder protection measurement and control device can send out the off-limit alarm signal to remind the operation and maintenance personnel to deal with it in time.

Backup automatic power supply function: When the backup power supply is normal, the feeder protection measurement and control device can automatically input backup power to improve power supply reliability.

In summary, REF615 feeder protection measurement and control device has a variety of uses in the power system, not only can quickly remove the fault, protect the stable operation of the power system, but also can achieve fault location, fault type identification, communication, automatic reclosing, load management, off-limit alarm and backup and self-casting functions. The realization of these functions is helpful to ensure the stable operation of the power grid and the safety and reliability of the power supply.
