IEC 61850是針對變電站內通信的最新國際標準。施耐德電氣專家10年來積極參加IEC和UCA工作組的活動來開發此項新的變電站通信技術，以支持此最新的國際標準。

保護電驛能夠基於關於變電站總線的IEC 61850 8-1標準與PACiS變電站控制系統進行集成，同時能夠基於IEC

61850 9-2過程總線標準與我們自己的或其它廠商的合併設備進行銜接，使施耐德電氣能夠針對您的變電站提供完全符合IEC 61850標準的解决方案。

施耐德電氣可以提供解决方案來使常規的或不同的傳統變電站自動化系統變爲符合IEC 61850標準的變電站自動化系統。基於乙太網UCA2架構供貨的保護電驛可以輕鬆升級到IEC 61850標準，同時可通過使用“proxy”服務器來集成支持其它通信協議的保護電驛。

The world in the next 40 years would require far more energy but in an ever more sustainable way

再生能源為何要使用儲能系統


Example of frequency variation

(EDF source)

Zone of Escalation

• 愈多的再生能源併入電網，將造成電網不穩

• 頻率如果劇降而沒有儲能系統，將會使系統跳脫

• 設計儲能系統，主要的目的是進行區域平衡，提供新的方法進行電力雙流動管理，可遞延變電站或饋線投資

Introduction to Power Plant Controller - PPC

Property of Schneider Electric |


Power Plant Controller Main functions

The PPC fulfils the Grid Utility requirements regarding active and reactive

power regulation for large PV power plants

The PPC uses closed control loops for high-precision control at the Point of

Connection.

Embedded reactive power operation modes are:-Voltage Control

-Power Factor Regulation

-Reactive Power

Embedded active power operation modes are:-Frequency Control

-Curtailment

-Ramp rate

support functions

Industrial IoT


Power Plant ControllerScalability

In order to comply with worldwide Grid Utilities, the PPC offers great scalability :

Embedded operation modes can be adjusted for each countries

The PPC functions can be adjusted depending the PPC type : PPC Universal

or PPC Evolution.

The Point of Connection can be on Medium or High voltage

The PPC can communicate with the Grid Utility through various

communication protocols (DNP3, IEC61850, IEC104, Analog and Digital

Input/Output, …)

Voltage control and reactive power operation modes can be activated during

the day and during the night
