Field Test Verification of the Series Static Voltage Compensator for Power Distribution Line

SUMMARY This paper describes two types of rotary loop flow controller, one is series type and the other is unified power flow controller (UPFC) type. Both of them can maintain the suitable voltage level of distribution system even with a large and uneven penetration of distributed generation. The configurations of proposed controllers are essentially same as wound rotor induction machine with no slip rings. The proposed controllers are less costly, more efficient, and more tolerant to overvoltages/currents as compared to power electronics‐type controllers. Further, UPFC‐type rotary loop flow controller has additional advantages like relatively smaller capability and ability to control reactive power than the series type of rotary loop flow controller. The proper functioning of the proposed controllers is confirmed through simulations and experiments.

“…A problem in recent years has been instantaneous voltage drops due to faults or abrupt changes of load in power systems, with stoppage of equipment in automated factories and semiconductor manufacturing plants. In order to maintain voltage at the load end, the user power reception point, at a constant level even during an instantaneous voltage drop, series voltage compensators are used [1].

The abbreviation SVC is used as an abbreviation for for a series voltage compensator [1,2], and the abbreviation SVC will be used in this paper as well. An SVC is a device that generates a voltage synchronized with the system voltage by means of a PWM inverter, and superimposes it on the deficient voltage by means of a transformer inserted in series into the system.…”

In this paper, we propose a strategy for the design of the LCR filter in a series voltage compensator and investigate our method by performing simulations and experiments. In the proposed method, first, the inductance L f is derived from the ratio of the maximum amplitude of the ripple current to the amplitude of the fundamental current, which is denoted as {%I ri p }. Second, the capacitance C f is derived from the ratio of the ripple voltage to the fundamental voltage. Third, the resistance R is determined from the rate of decrease of the carrier frequency component and the settling time. C⃝ 2014 Wiley Periodicals, Inc.

“…On the other hand, voltage/current profile databases are built by multipoint measurements using switches with built-in sensors and other techniques. This approach aims at comprehension of the actual operating conditions in high-voltage distribution lines, and creation of a development environment for new methods of sending voltage control [3][4][5][6][7].…”

Determination of optimal sending voltage profile in distribution systems with distributed generators

et al. 2007

SUMMARYSending voltage profile of distribution feeder is controlled by changing a tap of distribution transformer. In a distribution network with distributed generators, for reasons of effect of reversed flows from them and existence of a great number of sending voltage profile candidates, it is not easy to control sending voltage profile within the acceptable voltage limit. In this paper, in order to determine the optical sending voltage profile of distribution transformer in a distribution network with distributed generators, the authors propose a new method to determine the optimal sending voltage profile so as to minimize the total number of tap position's change per day under constraints of acceptable voltage limit. In the proposed method, after calculating acceptable range of three-phase voltage of distribution feeder, the optimal profile of tap position within the calculated acceptable voltage range is determined among these candidates by using reduced ordered binary decision diagram (ROBDD) which is an efficient enumeration algorithm. In order to check the validity of the proposed method, numerical simulations are carried out for a distribution network model with a distributed generator.
