功率因素改善之電力電容器，其電容值可能因系統過電壓、環境溫度、頻繁投切或材料老化等因素而衰減，使電容器與系統短路阻抗所形成之並聯共振頻率產生偏移，提高諧波電流放大的可能性而導致電容器或其它電力設備因過電流而故障。傳統上，電力電容器之保養基於經濟因素採定期維護(TBM)方式，對於其電容值之衰減及並聯共振危機，無法即時得知並加以防範。
為解決上述問題，本論文建置一套以SCADA為基礎之電容器配電盤狀態維護與管理系統。電容器盤內之智慧型電子裝置(IED)、自動功因調整器(APFR)與溫度傳感器，用以量測包括開關投切資訊在內之系統與電容器相關參數，並透過Modbus TCP/IP通訊協定，將資訊傳回後端之監控系統平台。在此平台，電容器配電盤狀態維護與管理系統已被成功開發，用以進行分析與決策。狀態維護與管理系統功能包含演算、保護、電錶與狀態顯示四大部分，利用演算與狀態顯示功能，可即時呈現電容器的投切狀態與電容值，針對電容量的衰減做線上監測，則可預先發現可能的危險共振現象並加以防範。最後，應用模糊理論與證據理論找出電容器潛在故障因素。

Capacitance decay of power capacitors may be caused by many factors, such as system over-Voltage, high ambient temperature, frequently switching or material aging. It lead to deviate the parallel resonance which is determined by short-circuit impedance of system and equivalent impedance of load. It also may increase the probability of resonance due to harmonic issues and cause capacitors or other equipment harm by overcurrent. Traditionally, Time Based Management (TBM) of capacitor maintenance is introduced since economic consideration. Unfortunately, it not been able to find out capacitance values decayed and parallel resonance deviated in time.
In order to solve the mention problems, a Supervisory Control And Data Acquisition (SCADA)-based maintenance and management systems for capacitor banks panel is presented. Using the Intelligent Electronic Device (IED), Automatic Power Factor Regulator (APFR) and temperature module within the capacitor banks panel to measure the system and capacitor associated data, including the capacitor switching information, Then, those data will send back to SCADA platform using Modbus TCP/IP communication protocol. In this platform, a Condition Based Maintenance (CBM) and management systems for capacitor banks panel has been successfully developed to perform analysis and decision making. The main function of the system includes calculation, protection, metering and state display. By calculation and state display function, the capacitance and operating status of capacitor can be presented in time. In such a way, it became possible to monitoring capacitance online. Therefore, the dangerous parallel resonant can be discover and prevent in advance. Finally, the fuzzy and evidence theory are apply to reveal the inherent failure factors of capacitor.
