Abstract

This article presented multi-level swell voltage control for minimizing the damage to an on-grid system between 1.3 to 1.8 pu. in compliance with the value regulated by IEEE and IEC standards. A window comparator circuit and comparator circuit with hysteresis transistor were used as the voltage detector and the excessive pulse entering the multi-level control of the load. According to the designed function in every stage in the form of fail-safe AND gate, the system was set for this case by turning to the fail-safe mode in order to prevent a fail-dangerous mode that might harm the electric system if the device in the detection circuit is deprived of qualification which is against the condition. Due to the Failure Mode and Effect Analysis (FMEA) in accordance with IEC-6196-1, the function prevents the electric and electronic devices of the on-grid system from damage. The design and installation of the electric protection device SVSS has a parallel-connect with the electric system without the concern of the load’s current.

Highlights

In recent years, electronic technology has progressed consistently, becoming a major mechanism in the creation of many innovations including electric and electronic appliances, communication devices, and the smart on-grid power management network, which conforms to the State policy that encourages the development of the smart on-grid power network system in every region of the country in order to support the challenge of energy stability problems as well as global climate change
The detector consists of Window Comparator Multi-Stage (WCS) that scopes the range of multi-levelled output voltage and Comparison with Hysteresis (CH) that detects the hysteresis voltage and pulse
This article demonstrates the multi-level swell voltage control for minimising damage to the on-grid system that connects the electric power of the electricity authority with 3-stage swell voltage control

Summary

INTRODUCTION

Electronic technology has progressed consistently, becoming a major mechanism in the creation of many innovations including electric and electronic appliances, communication devices, and the smart on-grid power management network, which conforms to the State policy that encourages the development of the smart on-grid power network system in every region of the country in order to support the challenge of energy stability problems as well as global climate change. The installation of an on-grid solar power system [1,2] in a small house or rooftop PV system installation is a small-size electric generation system from 3-10 kw/household This could be further developed for commercial use
