Application

Application of active harmonic filter device in power distribution system of water treatment industry

With the rapid development of the pharmaceutical industry, many new and advanced equipment required by the pharmaceutical industry have also emerged. Pharmaceutical companies have a large number of pump and motor loads, and many of them are equipped with frequency converters. The extensive application of frequency converters has greatly increased the harmonic content in the distribution system. At present, the rectification link of most frequency converters uses 6-pulse rectification to convert AC into DC, so the harmonics generated are mainly 5th, 7th and 11th. At the same time, pharmaceutical companies usually have laboratories and automated production lines, with a large number of precision equipment. In many cases, these equipment are both generators and victims of harmonics. Harmonics will affect the normal operation of equipment in the laboratory, causing the ongoing experiment to fall short; harmonics will also affect the intelligent controller and PLC system of the automated production line, causing automatic control equipment to malfunction. In many laboratories and automated production lines of pharmaceutical companies, the influence of harmonics has caused equipment failure. Therefore, the harmonic problem of pharmaceutical companies has a far-reaching impact and serious harm, and it is in urgent need of governance.

 

Research sites and laboratories As an important biopharmaceutical research site, laboratories have a large number of sensitive equipment that requires a clean power grid environment to ensure the normal operation of the system. Generally, they involve high-tech instruments, precision instrument measurement equipment, switching power supplies, rectifier inverters, UPS/EPS, etc., which are also large harmonic sources. Due to the characteristics of the load, laboratories and other places with a large number of switching power supply loads will produce obvious 3rd, 5th and 7th harmonics. Special attention should be paid to the impact of the 3rd harmonic current on the neutral line.

Automated production line Fermentation is an important part of the production of APIs, so it is inseparable from the core of the fermentation tank. With the continuous expansion of product output, the continuous updating of new processes and the continuous increase of new varieties, different requirements have been put forward for the control method, stirring frequency and time adjustment of the fermentation tank. In view of the situation of heavy and large loads, large power consumption and long fermentation cycle, fermentation production enterprises have also adopted various methods in recent years and carried out a lot of equipment transformation. Frequency conversion speed regulation is the best way to meet the production process requirements and save energy and reduce consumption. However, with the continuous improvement of the degree of automation, the degree of power pollution of automation equipment is getting worse and worse, and the corresponding interference to the automatic control system is getting stronger and stronger. The requirements for power filtering, purification and obtaining relatively stable green power are also getting higher and higher. At present, the rectification link of most frequency converters uses 6-pulse rectification to convert AC into DC, so the harmonics generated are mainly 5th, 7th and 11th.

On-site case

Taking a biopharmaceutical power quality management project in Shandong Province as an example, according to feedback from the responsible personnel of the plant, the comprehensive office building of the plant frequently tripped. In addition, the reactor in the capacitor cabinet of the biopharmaceutical production workshop distribution room was burnt and the N line cable was overheated. The main reason was found. It was estimated that the comprehensive office building and the production workshop respectively involved variable frequency air conditioners, computer communication equipment, LED lighting and pumps and other loads, which would generate harmonics during operation and affect the entire power supply and distribution system. The distribution room where the comprehensive office building and the production workshop are located is measured, and corresponding management plans are given according to the corresponding power quality data.

 

Harmonic measurement data of the power distribution room of the comprehensive office building

	Current	Current distortion rate	Harmonic content	3rd harmonic	5th harmonic	7th harmonic
A	346A	22.3%	77.16A	29.4A	58.9A	35.9A
B	323A	20.8%	67.18A	16.4A	55.7A	29.4A
C	320A	22.6%	72.32A	21.7A	57.1A	35.2A

Harmonic measurement data of the power distribution room in the production workshop

Harmonic measurement data of the power distribution room in the production workshop
	Current	Current distortion rate	Harmonic content	3rd harmonic	5th harmonic	7th harmonic
A	152.71	88.03%	134	78.1	52.85	32.54
B	130.14	81.9%	106	63.56	42.39	27.81
C	155.84	83.54%	130	78.56	51.99	30.52
N	220.74			223.1

From the above two sets of measurement data, it can be concluded that the harmonics of the comprehensive office building are mainly 5th and 7th, and the current distortion rate is at most 22%. The 5th and 7th harmonics can be centrally managed in the power distribution room to eliminate the impact of harmonics on the entire power supply and distribution system, transformers, capacitor cabinets and other electrical equipment, thereby ensuring normal biopharmaceutical production; the harmonics in the power distribution room of the production workshop are more serious, and the 3rd and 5th harmonics have exceeded the national GB/T14549-1993 "Power Quality Public Grid Harmonics" 0.38KV system harmonics and harmonic current value standards. The on-site capacitor cabinet is connected in series with a 7% reactance, and the 3rd and 5th harmonics flow into the capacitor cabinet. The harmonic current is superimposed on the fundamental current of the capacitor, which increases the operating current of the capacitor and increases the temperature rise, causing overheating and reducing the service life of the capacitor or damaging the capacitor. Since the 3rd harmonic belongs to the zero-sequence harmonic current, the three-phase vector angle is consistent, and it will be linearly superimposed on the N line. The current of the N line is about 223A, which has exceeded the current value of the phase line. Excessive current of the N line will cause the neutral line to overheat, insulation aging, and grounding fault, which will lead to power outage and even electrical fire. Active filtering devices can be used to treat them on the spot at the end. Using DSP+FPGA full digital control mode, parallel connection in the system can fully compensate for 2 to 51 harmonics or specific harmonics; it can eliminate all harmonics in the system, prevent harmonics from damaging the N line, protect the line, and prevent fire.
