About Hoorpendar
Building equipment for power plants, dams and oil and gas since 1999
Hoorpendar Computer Technology Industries, a knowledge-based company founded in 1999, designs and manufactures specialised electronic equipment and delivers electrical, control, automation and instrumentation projects. We have completed many EPC projects in oil and gas, water and power, and steel, and in most of them we designed and built the hardware ourselves.
Our clients are dams and power plants, oil and gas operators, the national meteorological network and other key industries. Most of what we build has to run continuously in harsh conditions: heat, vibration, humidity, strong magnetic fields and surges from switching and lightning. In power plant control, drinking water supply or an oil and gas pumping station, even a short stop is expensive.
Many of our projects were research programs carried out for the first time in Iran, among them generator excitation for a power plant, a digital hydro-turbine governor, a two-axis laser crydoscope and a meteorological data switching network. Few companies both deliver electrical, instrumentation and automation projects and design industrial electronics for series production. Hoorpendar does both.

Iran’s first domestically built static excitation system
We designed and built the excitation unit for a hydroelectric generator. Since then we have produced many static excitation systems for generators and synchronous motors, one of them rated at 1,200 A.
2001–2003
Intelligent control of drinking water transfer
We designed a fully redundant control system that automatically regulates water flow from a dam to a metropolitan area, and built its equipment ourselves.
2005–2006
Laser crydoscope for dam monitoring
It records dam-body movement on two axes (X and Y) to within 0.01 mm, without touching the structure.
2007–2011
Excitation and AVR for 3.5 MW synchronous motors
We built static excitation control and starters for synchronous motors at oil and gas pumping and compression stations. In 2017 we delivered 40 more excitation control units for the same motors.
2012–2013
Iran’s first digital hydro-turbine governor
In a research program we designed and built the PLC-based DHTG-300 digital governor, and gained our know-how in turbine speed control, hydraulics and servo valves along the way.
2013
800 alarm annunciator signals
We built and delivered alarm annunciators covering 800 signals for the plants of an oil and gas operator.
Grid test
A successful black-start test
Part of a province was fully disconnected, and a hydro plant running Hoorpendar’s SECON-2000 excitation and DHTG-300 governor restored it in island mode, holding frequency and voltage through load steps of up to 2.5 MW.
2017
120 pressure-to-current converters in one contract
We delivered 120 PI-315 units so that older pneumatic instruments could connect to electronic control systems.
2018 onward
Gas turbine control units
For an oil operator we have designed and built more than ten models of gas turbine control unit, which measure speed and temperature and control the fuel valve. The work is still going on.
2021
Contactless position sensor at 60 bar
The sensor measures gas turbine inlet guide vane position and works inside the hydraulic actuator, at 60 bar, on an offshore facility.
2022
Locomotive generator excitation
We designed and built a locomotive generator excitation system, with switching converters and drivers made for it.
