Ningbo successfully developed the nation's most advanced power quality analyzer

2011-2-10 Source: China Exhibition Website of the instrument: Zhou Ji, Xian Zhang, Liu Yu, future hits: 2 "! The new instrument we really put plants 'disease' to cure the high-tech electric service really powerful!" On the 28th, the person in charge of Ningbo Baodijia Heat Treatment Plant called the local power supply department to express thanks. In recent years, due to the increase in orders, the plant's production capacity has increased steadily, and voltage instability has frequently occurred and production has been affected. Recently, Ningbo Electric Power Bureau experts used the newly developed "power quality analyzer" to monitor the power quality of the plant, the results show that the total harmonic voltage exceeded, through the timely installation of filter devices, to solve the problem of voltage instability.

It is reported that this "power quality analyzer" is a new test equipment developed by the Ningbo Electric Power Bureau to help users grasp power quality in real time and provide users with solutions in a timely and accurate manner.

In Ningbo Dongfang Ruishi Residential Area, the author saw this instrument. It is a small iron box about 30 cm square and 10 cm thick with a LCD screen and a row of operation buttons. The on-site technicians connected the analyzer to the community-specific voltage generator and turned on the switch. The indicator light began to flash and the green LCD screen began scrolling to display multiple professional data. “The analyzer collects a complete set of data every 5 seconds. These parameters directly describe the current power load situation of the entire community.” said Liu Yu, head of the security service department of Jiangdong Power Supply Bureau responsible for the test.

According to reports, the core technology of this instrument is a powerful power quality analysis system, which is equivalent to the brain of the instrument. At present, the same type of power quality analyzer in China is generally re-sampled and lightly analyzed. The new system developed by Ningbo Power Industry Bureau not only combines a high-speed, high-precision sampling system, but also is equipped with a wealth of user power quality assessment software. In the shortest time, online processing and analysis are performed on the collected data to generate graphically clear and intuitive reports, and to provide detailed and targeted rectification solutions. Relevant power experts said: "This capability is currently second to none in the country, and it is very effective for large consumers, especially high-end users with higher power quality."

This clever use of electricity “doctor” for one month has been field diagnostics for users such as Ningbo Baodijia Heat Treatment Plant, Ningbo Yunsheng Group, Modern Decoration Market and Ningbo Dongfang Ruishi Residential Area, and provided according to the test results. Tailored power optimization solutions.
