This thesis presents an analytical formulation of the frequency domain characteristic of the Static Synchronous Series Compensator (SSSC). It mathematically proves that the SSSC has a frequency domain impedance characteristic similar to that of a capacitor. This thesis also investigates different controllers of the SSSC-Vq (Voltage as a reference) andXq (Impedance as a reference) controllers. The results of the analysis show that the two controllers display significantly different frequency domain characteristics for the same amount of reactive compensation. The frequency domain characteristics of the Vq controlled SSSC is a function of the operating point only, whereas the frequency domain characteristics of the Xq controlled SSSC is a function of the operating point as well as controller parameters. Comparison of analytical and simulation results shows very close agreement. The analytical model derived herein may be used to model and design an SSSC and to study occurrence of subsynchronous resonance (SSR) in the SSSC. File Size: 7MB.

Controlling the power flow in new configuration of electrical distribution system is source of advantages. Because of the enormous demand on power system has initiated the system to load heavily which leads to voltage unbalance conditions. The results show the voltage profile improvement on all busses along with the total power losses reduction. One of the great impacts of D-SSSC is balancing the power flows of connected feeders, avoiding congestion of feeders and cables damages.
When a three phase fault is introduced just after 0. Operational Advantage of the GE STATCOM Solution The operational advantages of this design decision can be clearly seen in the two figures below.
A profound improvement in the steady state stability of 400kV MIS grid is thus achieved by using SSSC. This system sometimes needs to reverse the power flow in the line despi. Under heavy loaded conditions there may be insufficient reactive power causing the voltages to drop.
The rate of dissipation of transient energy is usually used as a tool to measure dynamic system damping. In addition experimental results obtained with a small-scale MMC prototype, with 03 submodules per arm, will be presented to demonstrate the feasibility of the compensation strategy proposed here.
GE supports the entire value chain with a full range of competencies, eliminating project and logistical complexities of multiple vendor projects• The fiber optic interface enables the boards in different racks to communicate with each other as if they were installed in the same rack without any software change.
Distribution Static Synchronous Series Compensator D-SSSC is able to control the power flow between two feeders from different substations. The uniqueness of GE's solution is the larger DC capacitance, a re-usable by-pass switch and industry leading Model-Based design STATCOM control platform. I have been working in an electric distribution utility for more than a decade.
It also presents some of the results of TNA simulations carried out with an SSSC hardware model.
A previous paper describes a new concept for mitigation of the phenomenon of subsynchronous resonance SSR based on asymmetrical series capacitor compensation at SSR frequencies.
All major STATCOM components are vertically integrated within advanced manufacturing facilities, certified to ISO 9001:2015 Environmental Standards, ISO 4001 and OHSAS 18001 An unrivaled DC voltage source for a better STATCOM The function of a STATCOM system is to provide reactive compensation to the grid when it is needed most, during fault and transient conditions.
As a result, the effect of the voltage drop on power transmission is offset.
In addition to series reactive compensation, with an external dc power supply it can also compensate the voltage drop across the resistive component of the line impedance.
