Hybrid Active Filter for Reactive and Harmonics Compensation in a Distribution Network

The problem of reactive power and harmonics in the medium voltage level of a power distribution system is considered in this paper. Reconfiguration of the power delivery network imposes new constraints in a distribution substation so that the reactive compensation should be increased. The alternative of a shunt hybrid active filter connected to the 13.8-kV level to enhance the power quality is analyzed in this paper. This proposal uses the existing capacitor bank to build a hybrid filter in which the complementary compensation is performed by the active filter. The performance of the hybrid filter is evaluated with extensive simulations considering reactive power, harmonics, and unbalance compensation. It shows very good behavior in steady-state and transient conditions.

Hybrid Power Filter to Enhance Power Quality in a Medium-Voltage Distribution Network

This paper deals with the problem of reactive power and harmonics in a standard medium-voltage (MV) distribution network. It proposes a simple and inexpensive solution to enhance power quality when a particular connection to the high-voltage transmission network is required. It presents the design of a hybrid active filter topology connected to the MV level of a power distribution system. Its main task is to regulate a 132-kV voltage level. Reconfiguration of the power delivery network imposes new constraints in a distribution substation so that the reactive compensation should be increased. The topology of a shunt hybrid active filter is analyzed. It is built with the series connection of a passive filter and a low-rated active filter. The proposed filter is directly connected to a 13.8-kV level with no need of a step-down transformer. The possibility of different levels of reactive power compensation is implemented. The proposal shows very good performance for different load demands.

Comparison of active filters topologies in medium voltage distribution power systems

This paper presents the design of different topologies of active power filters to compensate reactive power and harmonics in the medium voltage level of a distribution power system. One pure active filter and two hybrid topologies, are implemented. A pure active compensation is obtained with a Shunt active power filter (SAPF). The shunt combination of SAPF and passive filter, form one of the hybrid topologies implemented, named shunt hybrid active power filter (SHAPF). The other hybrid topology, called hybrid shunt active power filter (HSAPF), connects the active filter in series with two shunt passive filters. Simulation for different load demands and distortions are performed. Finally a comparative evaluation of the different filters is carried out.

Reactive and Harmonics Compensation in a Medium Voltage Distribution Network With Active Filters

This paper presents the design of a shunt active filter to compensate reactive power and harmonics in the medium voltage level of a power distribution system. Reconfiguration of the power delivery network imposes new constraints in a distribution substation so that the reactive compensation should be increased. The alternative of shunt active filter compensation connected to the 13.8 kV level is analyzed. Two alternatives are proposed, the first one considers full compensation with the active filter while the second one uses the existing capacitor bank and builds the complementary compensation with the active filter. In the last case, the capacitor bank is modified to make a 5th harmonic filter to avoid system resonances. Both proposals show very good performance.

Compensation with Hybrid Active Power Filter in an Industrial Plant

This paper presents the application of a hybrid active power filter for reactive and harmonic compensation at the level of Medium Voltage (MV) of an electrical network of an industrial plant. It is considered as control algorithm, the application of the d-q theory and performing the current measuring in the system, establishing a feedback control loop (feedback). It is analyzed a hybrid topology called Shunt Hybrid Active Power Filter SHAPF. This proposal uses an existing capacitor bank, transformed into a passive filter, and connected in series with the Active Filter to build a hybrid filter in which the compensation supplement is made by the active filter. We analyze different scenarios of operation. The topology has very good performance under steady state and transient.
