Engineering firms: projects wait for control specialists

Projects need control specialists, capacity is short

What happens. An engineering firm wins a project that needs a controls specialist for a few months, say predictive control, estimation or optimisation. Its permanent staff are booked, and the one expert is on another customer.

What it costs. The firm either turns the work down, stretches the schedule or staffs it with someone learning on the job. Customers notice the delay, and margin goes into rework.

Why the usual fix fails. Hiring for a peak is slow and leaves the firm with an idle position afterwards. Subcontracting to a large competitor risks losing the customer.

How a fixed-price remote diagnosis checks it. I take on a clearly bounded piece, for instance a review of a controller concept or a look at the customer’s logs. The fixed-price remote diagnosis gives you a result for a fixed fee, with a statement of what the next step would need, before you commit any team.

Energy supply of critical sites: resilience, autarky and grid faults

What happens. Hospitals, data centres and plants want to stay supplied when the grid fails. Engineering firms are asked to size and test microgrids, storage, generators and their control, and to show what happens in a fault.

What it costs. Wrong sizing means paying for capacity that is never used, or an island that collapses at the first fault. Simulations that nobody trusts delay the decision.

Why the usual fix fails. Rules of thumb for sizing ignore how the pieces behave together in the seconds after a fault. Detailed models are costly to build and to validate for each site.

How a fixed-price remote diagnosis checks it. I review the planned configuration and the site’s load records and ask which dynamics decide the outcome. The fixed-price remote diagnosis tells you whether a system simulation can answer the resilience question for this site, and what it would need to be believed.

Control concepts for grid-forming inverters are slow to develop

What happens. Inverters that form the grid, not just follow it, need control concepts that hold voltage and frequency when supply is weak. Engineering firms develop them in simulation models and are asked for results faster than the model-building allows.

What it costs. Concepts that were never tested against a weak or faulted grid cost redesign late in the project, when a hardware change is expensive.

Why the usual fix fails. Taking a published control scheme and adjusting its parameters rarely covers the grid conditions the customer will meet. The people who combine power-electronics and grid knowledge are few.

How a fixed-price remote diagnosis checks it. I review the model and the concept: which grid conditions were tested and which were not. The fixed-price remote diagnosis tells you whether the concept is likely to hold across the range the customer needs, and what the next simulation campaign should cover.

Wind-turbine control for efficiency, stability and loads needs experts

What happens. Wind-turbine controllers must raise yield, keep the turbine stable and limit loads on blades, tower and drive train, all at once. Engineering firms that develop these algorithms for turbine makers cannot find enough people who know the three goals together.

What it costs. Weaker control means energy lost and parts that wear faster, and development schedules slip while roles stay open.

Why the usual fix fails. Tuning gains per turbine type by hand trades one goal against another without showing the best compromise. Remote work is possible, but the knowledge must be there.

How a fixed-price remote diagnosis checks it. I have worked on wind-turbine control at IAV, an automotive and energy engineering firm. The fixed-price remote diagnosis reviews your simulation or measured data, and shows whether a better compromise between yield and loads is within reach and how to test it.

High-voltage direct-current and grid modelling work comes in peaks

What happens. Projects for direct-current links and grid connections need power-system models: studies for the grid operator, for the equipment maker, for the permit. The work arrives in waves and needs people with rare skills.

What it costs. Roles stay open for months while a study deadline runs. Missed deadlines hold up customers’ permits and connections.

Why the usual fix fails. Hiring for a wave leaves a gap afterwards, and training a power engineer on grid models takes longer than the wave lasts.

How a fixed-price remote diagnosis checks it. I take a defined modelling or review task from your project data, with a fixed result. The fixed-price remote diagnosis shows what can be answered from your existing models, and how much of a study could be moved to outside capacity.

Vehicle control development needs model-based design and validation

What happens. Automotive control functions are developed in models, then tested step by step: software in the loop, then hardware in the loop. Engineering firms need people who can build the model, design the controller and run the validation chain.

What it costs. Gaps in the chain show up late: a function that worked in simulation misbehaves on the hardware rig, and the delay lands on the customer’s launch date.

Why the usual fix fails. Adding testers does not fix a controller concept that was never robust. A larger simulation team slows down because the experts are the bottleneck.

How a fixed-price remote diagnosis checks it. I review a control function and its validation set-up: the model, the test cases, the logged behaviour on the rig. The fixed-price remote diagnosis tells you where the concept is weak, whether a model-based redesign would help, and what the validation should cover.
