Smart grid temperature measurement

Smart grid belongs to the power system, which includes power plants, jaringan tegangan tinggi, gardu induk, stasiun distribusi, dll.. Secara khusus, there are power equipment such as generators, transformator, kabel listrik, saklar, dll.. These devices typically operate in environments with high voltage, medan listrik yang kuat, thermal loads, dll., dan lingkungan kerja tidak berawak dan tidak diawasi. As an engineering infrastructure system, the power grid involves the electricity demand of thousands of households, and the operating temperature of power facilities and equipment is an important factor in ensuring the safe operation of the power grid. Whether it is power cables, transformator, or other electrical equipment, sebagai komponen penting dalam sistem tenaga listrik, local overheating or arc sparks may occur due to some circuit problems or external factors, leading to fires and causing huge economic losses. Karena itu, in order to avoid such malignant events, sangat mendesak untuk melakukan pemantauan suhu peralatan listrik secara komprehensif.

Saat ini, traditional PT100 temperature sensors are not only unsuitable for strong electromagnetic working environments, but also pose significant difficulties for long-distance multi-point detection. In response to the shortcomings of traditional detection methods, itu pengukuran suhu serat optik terdistribusi method that has emerged in recent years combines backward Raman scattering effect and optical time domain analysis (OTDR) technology to use sensing fibers to achieve a distributed measurement of temperature field. Dibandingkan dengan metode pengukuran suhu tradisional, serat optik terdistribusi temperature sensors have the advantages of high sensitivity, interferensi anti elektromagnetik, long-distance multi-point detection, dll.. Karena itu, they can be widely used in temperature monitoring and fire alarm of power systems, angkutan kereta api, terowongan tambang batubara, and large buildings.

Pengukuran suhu serat optik kabel

The power communication optical cable is a neural network for automatic control of the “empat jarak jauh” of the smart grid. Once subjected to abnormal external temperatures or even fire damage along the way, the consequences are extremely serious. Sensor suhu serat optik is a new technology in temperature measurement and one of the most widely used sensors in industry. The emergence of distributed fiber optic temperature sensors has greatly reduced the cost of obtaining unit information, which is undoubtedly a revolution for temperature sensors based on electrical signals and point type fiber optic grating temperature sensors. Distributed fiber optic temperature sensing technology utilizes optical fibers to measure the temperature field distribution in a continuous space several tens of kilometers along the fiber optic path, providing a feasible new means for temperature field measurement and control in harsh environments such as strong electromagnetic fields, high voltage and current, flammable and explosive materials, and complex geometric spaces. Karena itu, distributed fiber optic temperature sensors have received widespread attention due to their own characteristics, and research on distributed fiber optic temperature sensing systems has important theoretical significance and application value. Fiber Distributed Temperature Monitoring (DTS), Distributed Temperature Sensing）， Also known as distributed fiber optic temperature measurement, temperature monitoring is achieved based on the principle of optical time domain reflectometry (OTDR), Efek hamburan Raman, and Brillouin scattering effect, which are sensitive to temperature. The entire system uses fiber optic as the carrier of sensitive information sensing and signal transmission, and has the characteristics of continuous temperature measurement, pengukuran suhu terdistribusi, pengukuran suhu waktu nyata, interferensi anti elektromagnetik, keamanan intrinsik, pemantauan jarak jauh, sensitivitas tinggi, instalasi mudah, umur panjang, dll.. It is widely used in industries such as pipelines, terowongan, kabel, petroleum and petrochemicals, and coal mines.
