CONTACT US INDUSTRIES SERVICES PRODUCTS CAREERS ABOUT US GOVERNORS L&S Electric’s Governor History In the mid-1980s, L&S Electric began its revolutionary approach of retrofitting obsolete proprietary governors with solutions based on commercial off-the-shelf (COTS) equipment, such as programmable logic controllers and industrial hydraulic equipment. From 1998 through 2002, L&S greatly enhanced its engineering staff by hiring several Woodward hydro governor industry experts. From 2000 to 2005, L&S developed pre-engineered mechanical and hydraulic governor equipment such as EHI (electric hydraulic interface), high-volume main distributing valve (400 to 15,000 liter/min), high flow pump unloader valve, air over oil upclosing float valve, low-pressure accumulator / HPU instrumentation, kidney loop filtration system, MOST (mechanical overspeed system) and SSG (Speed Signal Generator). In 2007, the industry-leading LS-MRT 1.0 (multiple runner type) pre-engineered, configurable hydroelectric governor controller was released. In 2008, we finished the design of our IEEE compliant, pre-engineered N-Series governor hydraulic power unit (HPU) designs to cost-effectively meet the needs of the hydroelectric industry. Next-generation LS-MRT 2.0 was released in 2012. The L&S Electric LS-AGS (advanced governor system) hydroelectric governor was released in 2018. Hydro Plant Governor system challenges and solutions Typical challenges Unscheduled downtime due to unreliable obsolete equipment Replacement parts are expensive or not available Systems do not meet current regulatory agency performance requirements Older technology does not have adequate diagnostics for effective troubleshooting L&S solutions With over 30 years of experience, L&S Electric is one of a few full-service companies that can offer a complete design, system integration, and service of Governor control, mechanical and hydraulic systems for small to large hydro plants. Since the early 1980s, we have supplied digital hydraulic governor products and services for over 750 hydroelectric generating units, ranging in size from 75 kW to 600 MW With a staff of over 60 engineers, designers and manufacturing personnel dedicated to Power Control Solutions with expertise in Control, Electrical, Mechanical, and Hydraulic Systems Our designs have always been based on commercial-off-the-shelf open architecture hardware that provides a flexible and cost-effective alternative to proprietary systems. Designed with proven technologies and validated IEEE models that meet or exceed industry standards and regulatory agency requirements. User-friendly interfaces include advanced monitoring and control features. Extensive diagnosis allows you to service equipment down to the module level with your in-house resources. Complete line of governor main distributing valves (200 to 15,000 L/min) Pre-engineered hydraulic power units designed specifically for hydroelectric governor applications. Entire governor system (controller and hydraulics) are fully tested and simulated in-house lab per IEC-60308 and ASME-PTP-29 Knowledgeable staff that takes the time to understand your specific situation and recommend practical, cost-effective solutions.
