The use of, both, static as well as dynamic compensators together may give cost-effective reactive power compensation for predefined transient limits of voltage response. This paper presents the pricing of reactive power compensation under steady-state and dynamic conditions of a system with fixed capacitor (FC) and STATCOM.
2.1. Characterization of the IES The reactive power compensation system was designed to avoid resonance problems and voltage variations in an IES with a predominant use of electric motors and variable speed drives. This IES has also installed new production lines to increase electrical loads.
1. Capacitor Banks: Capacitor banks are systems that contain several capacitors used to store energy and generate reactive power. Capacitor banks might be connected in a delta connection or a star (wye) connection. Power capacitors are rated by the amount of reactive power they can generate. The rating used for the power of capacitors is KVAR.
Solution 1 (S1): concentrated reactive power compensation with capacitor banks. Solution 2 (S2): distributed reactive power compensation with capacitor banks. Solution 3 (S3): concentrated reactive power compensation with harmonic filters. Solution 4 (S4): distributed reactive power compensation with harmonic filters.
Static VAR compensators Static VAR compensators (SVCs) contain shunt capacitors and reactors, which are controlled by thyristors. They provide solutions to two types of compensation problems normally encountered in practical power systems:
One of the main problems is that most of the power electronics used consume reactive power, which causes low power factor and system instability–a problem that has put power factor correction methods under development again. This article discusses the two most used reactive power compensation methods.
