1. Automation level of reactive power compensation device
The early reactive power compensation capacitor has a low degree of automation, which can't judge the change of power grid operation parameters, so it needs operators to switch in the operation process. When the frequency of network changes is high, the operation is more frequent, and the operators will feel difficult and increase the workload. With the rapid development of computer technology, the current reactive power compensation device has successfully adopted the microcomputer module for the operation and management of the device, with a relatively high degree of automation. It can judge the changes of power grid parameters in time, make reasonable automatic switching, and will not increase the workload of operators. The automation level has reached the requirements of power grid operation.
2. Reliability of reactive power compensation device
The technical performance and reliability of the early reactive power compensation device can not meet the operation requirements. Many improvements have been made to the current products. The operation of the products can reflect this problem. At present, many products put into operation in Xuzhou in 2000 are still in safe operation, and the operation life has exceeded 8 years.
The operation reliability of reactive power compensation device is also a problem that manufacturers pay more attention to. At present, many technical measures have been taken to improve the reactive power compensation device. Taking 10kV and 400V reactive power compensation device as an example, the following three factors are analyzed.
3. Influence of abnormal power quality
For abnormal power quality, such as over-voltage, harmonic, voltage flicker, waveform distortion and other interference factors, the current products have also taken protective measures, such as basically installing monitoring devices to monitor these factors; taking over-voltage protection measures and restraining harmonic, flicker, waveform distortion measures. However, due to the poor ability of electronic circuit components to resist over-voltage and voltage mutation, protection and isolation measures should be taken at the power supply end and signal input and output end of electronic circuit. It is recommended that manufacturers and relevant users pay attention to these measures.
