GE DS200SLCCG1ACC Product Overview

Speaking of the GE DS200SLCCG1ACC,it’s a longtime ally in the power generation control field!As the core control module of the EX2100 excitation system,it plays the role of”general commander”in generator control.Utilizing advanced DSP digital signal processing technology,it achieves high-precision voltage and reactive power regulation,quickly responding to any grid fluctuations to ensure stable unit operation.

Last year,a hydropower station in southwest China used the GE DS200SLCCG1ACC excitation control module in their 200MW hydro-turbine generator,which operated continuously for five years without any regulation failures.Most impressively,during a sudden grid frequency fluctuation,the module adjusted the excitation current within 10 milliseconds,preventing the unit from tripping.This rapid response capability is a lifesaver during power grid failures.

Compared to traditional analog excitation regulators,the DS200SLCCG1ACC’s advantage lies in its intelligence.It not only performs PID control but also automatically optimizes parameters based on unit operating conditions—this is the power of digitalization!

Main Features and Advantages

True Control Accuracy:The GE DS200SLCCG1ACC utilizes a 32-bit DSP processor,achieving a voltage control accuracy of±0.25%.One of my customers,using it in a peaking power plant,reported that this accuracy has increased their AGC regulation pass rate from 95%to 99.5%.

Exceptionally Fast Response:With a response time of less than 10ms,it instantly reacts to any grid disturbance.This speed is particularly critical during grid failures,effectively preventing the unit from losing synchronism.

Reliable Reliability:With a dual-channel redundant design,if the primary channel fails,the backup channel automatically takes over,with a switchover time of less than 20ms.A longtime customer reported that after installing this module,their unit has had no downtime due to excitation system failures in five years.The GE DS200SLCCG1ACC represents advanced excitation control technology.This robust control module features precise voltage regulation and fast response characteristics,ensuring stable generator operation in various power generation applications.With redundant architecture and comprehensive diagnostics,it provides reliable performance in critical power systems.

Application Areas

In the thermal power generation industry,the GE DS200SLCCG1ACC is a standard feature in excitation systems.It can be found in units ranging from 300MW to 1000MW.One customer reported that after using this control module,the unit’s voltage compliance rate reached 100%,and they received over 2 million yuan in additional annual grid assessment rewards.

It also excels in the hydropower sector.In hydro-turbine generator excitation control,its fast response characteristics are particularly well-suited for frequency-varying conditions.A friend at a hydropower plant reported that after installing the DS200SLCCG1ACC,the unit’s primary frequency regulation compliance rate was significantly improved.

Selection Guide

When selecting a model,first consider the unit capacity.The GE DS200SLCCG1ACC is suitable for small and medium-sized units.For extra-large units,a more advanced model should be selected.

Secondly,consider the grid requirements.If the grid is subject to strict assessments and requires high-precision regulation,this module can fully meet the requirements.

FAQ

Q:How do I switch channels?

A:The GE DS200SLCCG1ACC supports automatic and manual switching.Regular testing of the backup channel is recommended.

Q:What should I do if parameters are lost?

A:Back up the parameters to a USB flash drive immediately.It’s best to save two copies as a precaution.

Q:How do I resolve a communication interruption?

A:First check the network cable and then restart the communication module.This is usually a physical connection issue.

Customer Case Study

Last year,we helped a coal-fired power plant upgrade its excitation system.Their old analog regulator was constantly overshooting.After replacing it with the GE DS200SLCCG1ACC,not only did the regulation become more stable,but it also implemented AVC automatic control,generating over 20 million kWh more electricity annually.Related Products
