  • What are the characteristics of the power system power quality monitor?

    1. Passive filter: The passive filter of the power system has the advantages of low cost, simple structure, reliable operation and convenient maintenance. It is the main method of harmonic suppression and reactive power compensation used in the current power supply system. . However, it has disadvantages such as large volume, and the filtering effect is greatly affected by the system.
    2. Parallel active power filter: It can basically overcome the shortcomings of passive filters and introduces a new concept of dynamic compensation. In addition to compensating for harmonics, APF can also adjust a variety of power quality problems. To realize large-capacity harmonics or realize the diversity of active compensation functions, the APF needs to have a large device capacity. The research on the hybrid compensation scheme is currently in a stage of continuous development and gradual deepening. In-depth research on this type of regulator, and corresponding hybrid compensation measures with better technical and economic performance for different load conditions, will definitely play a positive role in improving power quality.
  • What is the main purpose of power quality monitoring equipment?

    Power quality monitoring equipment mainly includes the quality of voltage, frequency and waveform. The power quality online monitoring device mainly measures voltage deviation, voltage fluctuation and flicker, frequency deviation, harmonics and voltage asymmetry, unbalance, etc.
    Monitoring the reliability of power supply is also an important task. Power supply reliability refers to the ability of the power supply system to continue supplying power. It is an important indicator for evaluating the power quality of the power supply system. It reflects the degree to which the power industry meets the power demand of the national economy and has become a standard for measuring the economic development of a country. Power supply reliability can be measured by a series of indicators as follows: power supply reliability rate, average user outage time, average user outage times, system outage equivalent hours; my country's power supply reliability rate currently reaches 3 9 (ie 99.9%) in general urban areas ) Above, the average annual power outage time for users does not exceed 8.76 hours; the key urban central areas have reached more than 4 9s (ie 99.99%), and the average annual power outage time for users does not exceed 53 minutes.
